Card Reference
This chapter describes the Cisco ONS 15454 cards. It includes descriptions, hardware specifications, and block diagrams for each card. For installation and turn-up procedures, see Chapter 1, "Installation."
2.1 Overview
The cards for the ONS 15454 include common control cards, electrical cards, optical cards, and an Ethernet/Fast Ethernet card. Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 shelf assembly. The cards are then installed into slots displaying the same symbols (see the "Slot Requirements" section on page 1-36 for a list of slots/symbols). This overview provides a summary of the cards.
2.1.1 Common Control Cards
The four common control cards are the Timing Communications and Control (TCC/TCC+) card, the Cross Connect (XC) card, the VT1.5 Capable Cross Connect (XCVT) card, and the Alarm Interface Controller (AIC) card. The TCC is the main processing center of the ONS 15454 and provides system initialization, provisioning, alarm reporting, maintenance, and diagnostics. The XC/XCVT card is the central element for switching; it establishes connections and performs time division switching (TDS). The AIC card provides customer-definable alarms with its additional input/output alarm contact closures.
2.1.2 Electrical Cards
The electrical cards are the EC1-12, DS1-14, DS1N-14, DS3-12, DS3N-12, and the DS3XM-6 (Transmux). The EC1-12 card provides twelve STS-1 electrical interfaces. The DS1-14 card provides 14 DS-1 interfaces. The DS1N-14 card provides 14 DS-1 interfaces but can also provide 1:N protection when necessary. The DS3-12 card has 12 DS-3 interfaces and the DS3N-12 card has 12 DS-3 interfaces and 1:N protection capability. The DS3XM-6 card can convert six framed DS-3 network connections into 168 VT1.5s.
2.1.3 Optical Cards
The optical cards include the OC3IR 4 1310, the OC12IR 1310, the OC12 LR 1310, the OC12 LR 1550, the OC48 IR 1310, and the OC48 LR 1550 cards. The OC3IR 4 1310 card provides four intermediate or short-range OC-3 interfaces. The OC12IR 1310 card provides one intermediate or short range OC-12 interface. The OC12 LR 1310 card and the OC12 LR 1550 card each have one long-range OC-12 interface but operate at different wavelengths (1310 nm and 1550 nm, respectively). The OC48 IR 1310 card and the OC48 LR 1550 card each provide one long-range OC-48 interface and, like the OC12 LR cards, operate at different wavelengths (1310 nm and
1550 nm, respectively). The OC48 Extended Long Reach (ELR) cards provide the dense wavelength division multiplexing (DWDM) solution for the ONS 15454. There are eighteen OC48 ELR cards; nine operate in the red band on different wavelengths and nine operate in the blue band on different wavelengths.2.1.4 Ethernet Card
The E100T-12 card provides twelve switched, autosensing, 10/100 Base-T Ethernet interfaces. The Ethernet card reduces the need for certain external Ethernet aggregation equipment such as hubs or switches.
2.2 Electrical Card Protection
The ONS 15454 provides a variety of electrical card protection methods. This section describes the protection options. Figure 2-3 shows a 1:1 protection scheme and Figure 2-2 shows a 1:N protection scheme.
2.2.1 1:1 Protection
In 1:1 protection, a working card is paired with a protect card of the same type. If the working card fails, the traffic from the working card switches to the protect card. By default, the switched traffic stays on the protect card. shows the ONS 15454 in a 1:1 protection configuration; Slot 1 is protecting Slot 2, Slot 3 is protecting Slot 4, Slot 5 is protecting Slot 6, Slot 17 is protecting Slot 16, Slot 15 is protecting Slot 14, and Slot 13 is protecting Slot 12. Each working card is paired with a protect card.
Figure 2-1 1:1 Protection Configuration
2.2.2 1:N Protection
1:N protection allows a single card to protect several working cards. A DS1N-14 card provides protection for up to five DS1-14 cards, and a DS3N-12 card protects up to five DS3-12 cards. With the 1:1 protection offered by a standard DS1-14 card or DS3-12 card, protection extends only to the single working card paired with the standard protection card.
Currently, 1:N protection operates only at the DS-1 and DS-3 levels. 1:N protect cards must match the levels of their working cards. For example, a DS1N-14 protects only DS1-14 or other DS1N-14 cards, and a DS3N-12 protects only DS3-12 or other DS3N-12 cards. 1:N cards have added circuitry to act as the protection card in a 1:N protection group. Otherwise, the card is identical to the standard card and can serve as a normal working card.
The physical DS-1 or DS-3 interfaces on the ONS 15454 backplane use the working card until the working card fails. When the system detects this failure, the protection card takes over the physical DS-1 or DS-3 electrical interfaces through the relays and signal bridging on the backplane. shows the ONS 15454 in a 1:N protection configuration. Each side of the shelf has only one card protecting all of the cards on that side.
Figure 2-2 1:N Protection Configuration
2.2.2.1 Revertive Switching
1:N protection supports revertive switching. Revertive switching sends the electrical interfaces back to the original working card after the card comes back online. Detecting an active working card triggers the reversion process. There is a variable time period for the lag between detection and reversion, called the revertive delay, which you can set using the Cisco Transport Controller (CTC). (For instructions, see the "Configure the BLSR" section and the "Create a Circuit" section.) All cards in a protection group share the same reversion settings. 1:N protection groups default to automatic reversion.
2.2.2.2 1:N Protection Guidelines
Several rules apply to 1:N protection groups in the ONS 15454:
•
Working and protect card groups must reside in the same card bank (A or B).
•
•
•
The ONS 15454 supports 1:N equipment protection for all add-drop multiplexer configurations (ring, linear, and terminal), as specified by GR-253-CORE.
The ONS 15454 automatically detects and identifies a 1:N protection card when the card is installed in Slot 3 or Slot 15. However, the slot containing the 1:N card in a protection group must be manually provisioned as a protect slot because by default all cards are working cards.
For detailed procedures on setting up DS-1 and DS-3 protection groups, see the "Converting DS-1 and DS-3 Cards From 1:1 to 1:N Protection" section.
2.2.3 Electrical Card Protection and the Backplane
Protection schemes for electrical cards differ slightly depending on the Electrical Interface Assembly (EIA) type used on the ONS 15454 backplane. The difference is due to the varying connector size. For example, because BNC connectors are larger, fewer DS3-12 cards can be supported when using a BNC connector.
Caution
2.2.3.1 BNC Protection
When you use BNC connectors, the ONS 15454 supports 1:1 protection or 1:N protection for a total of four working DS-3 electrical cards. If you are using EC-1 electrical cards with the BNC EIA, the ONS 15454 supports 1:1 protection and a total of four working cards. Slots 2, 4, 14 and 16 are designated working slots. These slots are mapped to a set of 12 BNC connectors on the EIA. These slots can be used without protection for unprotected DS-3 access. With 1:N or 1:1 protection, slots 1, 3, 15 and 17 are designated for protection when BNC connectors are used. With 1:N protection, Slots 3 and 15 are also designated for protection when BNC connectors are used. Slots 5, 6, 12, and 13 do not support DS3-12 cards when you use the regular BNC EIA.
2.2.3.2 High-Density BNC Protection
When you use the High-density BNC EIA, the ONS 15454 supports 1:1 protection or 1:N protection for eight total working DS-3 electrical cards. If you are using EC-1 electrical cards with the BNC EIA, the ONS 15454 supports 1:1 protection and a total of eight working cards. Slots 1, 2, 4, 5, 13, 14, 16, and 17 are designated working slots. These slots are mapped to a set of 12 BNC type connectors on the EIA. These slots can be used without protection for unprotected DS-3 or EC-1 access. Slots 3 and 15 are designated for 1:N protection slots when BNC connectors are used with the High-density BNC EIA. Slots 6 and 12 do not support DS-3 or EC-1 cards when you use the High-density BNC EIA.
2.2.3.3 SMB Protection
When you use SMB connectors, the ONS 15454 supports 1:1 or 1:N protection. 1:1 and 1:N protection are available for the DS-1 and the DS-3 electrical cards. If you are using EC-1 cards with the SMB EIA, the ONS 15454 supports 1:1 protection. Working and protection electrical cards are defined by card slot pairs (note that the same card is used for working and protect modules; the protection of the card is defined by the slot in which it is housed). Each slot maps to a set of 12 or 14 SMB connectors on the EIA depending on the number of ports on the corresponding card. Any slot can be used without protection for unprotected DS-1, DS-3, or EC-1 access.
The DS1N-14 card can be a working or protect card in 1:1 or 1:N protection schemes. When used with 1:N protection, the DS1N-14 card can protect up to five DS1-14 plug-ins using the SMB connectors with the DS-1 electrical interface adapters.
2.2.3.4 AMP CHAMP Protection
When you use AMP CHAMP connectors, the ONS 15454 supports 1:1 or 1:N protection. Working and protection spans are defined by card slot pairs.
The DS1N-14 card can be a working or protect card in 1:1 or 1:N protection schemes. When used with 1:N protection, the DS1N-14 card can protect up to five DS1-14 plug-ins using the AMP CHAMP EIA.
2.3 Optical Card Protection
The ONS 15454 currently supports 1+1 span protection to create redundancy for optical cards. Working and protection spans are defined by card slot pairs. Optical cards in any two slots can be paired for protection. 1+1 protection pairs a single working card with a single dedicated protect card. If the working card fails, the protect card takes over.
With non-revertive 1+1 protection, when a failure occurs and the signal switches from the working card to the protect card, the signal stays switched to the protect card until it is manually switched back. Revertive 1+1 protection automatically switches the signal back to the working card when the working card comes back online.
2.4 Multiport Card Protection
For multiport cards such as the DS3-12 and the OC-3, the ports on the card in the protection slot support the card in the working slot. With 1:1 or 1:N protection (electrical cards), the protect card must protect an entire slot. In other words, all the ports on the protect card will be used in the protection scheme. With 1+1 protection (optical cards), protection can be assigned on a per-port basis. In other words, any number of ports can be assigned as protection ports. On a four-port card, for example, you could assign one port as a protection port (protecting the corresponding port on the active card) and leave three ports unprotected. Conversely, you could assign three ports as protection ports and leave one port unprotected.
Protection schemes can be modified using the CTC software. See the "Creating Protection Groups" section on page 3-26 for more information.
2.5 Unprotected Cards
Unprotected cards are not included in a protection scheme; therefore, a card failure or a signal error results in lost data. Because no bandwidth lies in reserve for protection, unprotected schemes maximize the available ONS 15454 bandwidth. shows the ONS 15454 in an unprotected configuration. All cards are in a Working state.
Figure 2-3 Unprotected Configuration
2.6 Timing Communication and Control (TCC/TCC+) Card
The TCC/TCC+ performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution, SONET Data Communications Channel (DCC) termination, and system fault detection for the ONS 15454. The TCC/TCC+ also ensures that the system maintains Telcordia timing requirements. The TCC and the TCC+ perform essentially identical functions but are not identical cards. The TCC+ is intended as a migration vehicle to future software releases. Figure 2-4 shows the TCC faceplate and Figure 2-5 shows a block diagram of the card.
Figure 2-4 TCC Faceplate
2.6.1 TCC/TCC+ Functionality
The TCC/TCC+ supports multichannel, high-level data link control (HDLC) processing for the DCC. Up to 48 DCCs can be routed over the Serial Communication Interface (SCI) and terminated at the TCC/TCC+. The TCC/TCC+ selects and processes ten DCCs to facilitate remote system management interfaces.
The TCC/TCC+ also originates and terminates a cell bus carried over the SCI. The cell bus supports links between any two cards in the system, which is essential for peer-to-peer communication. Peer-to-peer communication accelerates protection switching for redundant cards.
The node database, IP address, and system software are stored in TCC/TCC+ non-volatile memory, which allows quick recovery in the event of a power or card failure.
The TCC/TCC+ performs all system-timing functions for each ONS 15454. The TCC/TCC+ monitors the recovered clocks from each traffic card and two DS-1 (BITS) interfaces for frequency accuracy. The TCC/TCC+ selects a recovered clock, a BITS, or an internal Stratum 3 reference as the system-timing reference. You can provision any of the clock inputs as primary or secondary timing sources. A slow-reference tracking loop allows the TCC/TCC+ to synchronize to the recovered clock, which provides holdover if the reference is lost.
Install TCC/TCC+ cards in Slots 7 and 11 for redundancy. If the active TCC/TCC+ fails, traffic switches to the protect TCC/TCC+. All TCC/TCC+ protection switches conform to protection switching standards when the BER counts are not in excess of E10-3 and completion time is less than 50 ms.
The TCC/TCC+ features an RJ-45 10Base-T LAN port and an RS-232 DB9 type craft interface for user interfaces. The craft port runs at 9600 bps.
Caution
2.6.2 Unique TCC+ Functionality
The TCC+ is a memory-enhanced version of the first generation Timing Communication and Control card. The TCC+ will allow the ONS 15454 to scale from a multiservice OC-48 platform to a multiservice OC-192 platform in future releases without the need for an additional processor upgrade.
The enhanced memory of the TCC+ enable it to support the added features that future releases bring. Software Release 2.1 recognizes both processors; therefore, if a mixture of processors exist on the same shelf, the mismatch is flagged by the system. The TCC and the TCC+ can coexist on a network level but not on a shelf level. An upgrade to Release 2.2.0 software is required before you can install the TCC+.
2.6.3 TCC/TCC+ Card-Level Indicators
The TCC faceplate has eight LEDs. The first two LEDs are card-level indicators. The red FAIL LED indicates a TCC hardware problem. Replace the unit if the FAIL LED persists. The ACT/STBY (Active/Standby) LED indicates whether the TCC is active and providing the timing reference and shelf control (green), or is in standby to the active TCC (yellow).
2.6.4 System Level Indicators
The two red LEDs, CRIT and MAJ, indicate critical and major alarms in the system at the local terminal. The yellow MIN LED indicates a minor alarm. To provide first-level alarm isolation, the red REM LED illuminates when an alarm is present in one or several of the remote terminals. The green SYNC LED indicates that system timing is synchronized to an external reference.
Press the alarm cutoff (ACO) button to open the audible closure on the backplane. When the ACO function is activated, the green ACO LED illuminates. ACO state is stopped if a new alarm occurs. After the originating alarm is extinguished, the ACO LED and audible alarm control are reset.

2.7 Cross Connect Card
The Cross Connect (XC) card is the central element for ONS 15454 switching. It establishes connections and performs time division switching (TDS) at the STS-1 level between ONS 15454 traffic cards. The XC card faceplate, cross-connections, and functions are shown in Figure 2-6, Figure 2-7, and Figure 2-8.
Figure 2-6 XC Card Faceplate
The switch matrix on the XC card consists of 288 bidirectionsal ports. When creating bidirectional STS-1 cross-connects, each cross-connect uses two STS-1 ports. This results in 144 bidirectional STS-1 cross-connects. The switch matrix is fully crosspoint, non-blocking, and broadcast supporting. This allows network operators to concentrate or groom low-speed traffic from line cards onto high-speed transport spans and to drop low-speed traffic from transport spans onto line cards.
Figure 2-7 Cross-Connect Matrix
The XC card has 12 input ports and 12 output ports. Four input and output ports operate at either STS-12 or STS-48 rates. The remaining eight input and output ports operate at the STS-12 rate. An STS-1 on any of the input ports can be mapped to an STS-1 output port, thus providing full STS-1 time slot assignments (TSA).
The XC card works with the TCC/TCC+ card to maintain connections and set up cross-connects within the ONS 15454. Either the XC or XCVT is required to operate the ONS 15454. You establish cross-connect and provisioning information through the user interface on the TCC/TCC+. The TCC/TCC+ establishes the proper internal cross-connect information and relays the set-up information to the XC card.
For simplex operation, you can install a single XC card in Slots 8 or 10. A second XC can be added for redundancy. The card has no external interfaces. All card interfaces are provided through the ONS 15454 backplane.
Warning
2.7.1 XC Card-Level Indicators
The XC faceplate has two card-level LEDs. The red FAIL LED indicates a hardware problem. If the FAIL LED persists, replace the card. The ACT/STBY LED indicates whether the XC is active and carrying traffic (green) or in standby mode to the active XC (yellow).

2.8 Cross Connect VT Card
The XCVT card ( Figure 2-9) provides the same STS capability as a standard XC card. It provides non-blocking STS-48 capacity to all of the high-speed slots and non-bidirectional blocking STS-12 capacity to all low-speed slots. This creates a fully non-blocking, 288-port, STS-1 matrix.
The XCVT faceplate, cross-connections, and functions are shown in , , and .
Figure 2-9 XCVT Faceplate
The XCVT card adds VT1.5 cross-connect capability to the standard STS-level capability. This allows the XCVT card to manage up to 336 bidirectional VT1.5s or the equivalent of a bidirectional STS-12. The VT1.5-level signals can be cross connected, dropped, or rearranged. The TCC assigns bandwidth to each slot on a per STS-1 or per VT1.5 basis.
The XCVT card works with the TCC card to maintain connections and set up cross-connects within the system. Either the XCVT or XC is required to operate the ONS 15454. You can establish cross-connect and provisioning information through the user interface on the TCC. The TCC establishes the proper internal cross-connect information and relays the setup information to the XCVT card.
Figure 2-10 XCVT Cross-Connect Matrix
2.8.1 VT Mapping
The Cisco ONS 15454 performs Virtual Tributary (VT) mapping according to Telcordia GR-253 standards. shows the VT numbering scheme for the ONS 15454 as it relates to the Telcordia standard.
2.8.2 XCVT Hosting DS3XM-6
The XCVT card works with DS3XM-6 (transmux) cards. A single DS3XM-6 can
demultiplex, or map down to a lower rate, six DS-3 signals into 168 VT1.5s that the XCVT card manages and cross connects. XCVT cards host a maximum of 336 VT1.5s. In most network configurations, two DS3XM-6 cards are paired as working and protect cards.2.8.3 XCVT Card-Level Indicators
The XCVT faceplate has two card-level LEDs. The red FAIL LED indicates a hardware problem. Replace the unit if the red FAIL LED persists. The ACT/STBY (Active/Standby) LED indicates whether the XCVT is active and carrying traffic (green) or in standby mode to the active XCVT card (yellow).
2.8.4 XC/XCVT Compatibility
The XCVT supports run-time compatibility with the XC cross-connect both within a single node and within a ring of mixed XCVT and XC nodes. However, working and protect cards within a single ONS 15454 must be either two XC cards or two XCVT cards. If an XC card and an XCVT card are used together as a working and protect pair, the XCVT acts as an XC card. Both XC and XCVT systems are supported in unidirectional path switched ring (UPSR) and bi-directional line switched ring (BLSR) configurations. VT and STS-level cross-connect and protection management are also supported in either type of ring. Nodes that rearrange or drop VTs must use an XCVT. Nodes that only rearrange or drop STSs can use an XC. You do not need to upgrade STS-only nodes to XCVT in a ring that can handle both VT and STS drop/rearrangement. In this scenario, however, the XC must run Software Release 2.0 or higher.
When upgrading from XC to XCVT cards, the first XCVT card installed acts as an XC card until the second XCVT card is installed. For more information, see the "Upgrade XC Cards to XCVT" section.
If you want to create an STS-capable ring that allows VT drops at some nodes, all of the nodes in the ring must run Release 2.0 software or higher. The nodes that allow VT drops must use XCVT cards, and the nodes that do not allow VT drops can use any type of XC card.
When upgrading a system or ring to use the release 2.0 XCVT card, you must first upgrade the software to Release 2.0.

2.9 Alarm Interface Controller Card
The Alarm Interface Controller (AIC) card is an optional card that expands system management capabilities for customer-defined alarm I/O and orderwire. Figure 2-12 shows the AIC faceplate and Figure 2-13 shows a block diagram of the card.
Figure 2-12 AIC Faceplate
2.9.1 Customer-Defined Alarms
The AIC card provides additional input/output alarm contact closures. You can define up to four input and four output contacts. The physical connections are made using the backplane wire-wrap field. The alarms are defined using the CTC (for instructions see the "Provisioning the Alarm Interface Controller" section). Each alarm contact has a corresponding LED on the front panel of the AIC that indicates the status of the alarm. Input alarms are typically used for external sensors such as open doors, temperature sensors, flood sensors, and other environmental conditions. Output contacts are typically used to drive visual or audible devices such as bells and lights, but they can control other devices such as generators, heaters, and fans.
2.9.1.1 Provisioning I/O Alarm Contacts
You can program each of the four Form A input alarm contacts separately. They can be set to Alarm on Closure or Alarm on Open. The alarm severity can be set to any of the levels (Critical, Major, Minor, Not Alarmed, Not Reported). The alarm service level can be programmed to Service Affecting or Non-Service Affecting. A 63-character alarm description can be assigned for display by the CTC in the alarm log. The fan tray abbreviation for the alarm is not assignable. It reflects the generic name of the input contacts. The alarm condition remains until the external input stops driving the contact and you clear the alarm in CTC.
You can also program the Form A output alarm contacts separately. You can set them to close when the specified alarm condition is triggered; the default condition for output alarms is the open position. The alarm triggering conditions can be any ONS 15454 alarm condition including the user- defined input alarms, or triggering based on severity (i.e. trigger when any Major alarm happens), or remote alarm. You use pull-down menus in CTC to provision alarm-to-output-contact association; CTC organizes the alarms by category or by individual alarm. The output contact electrical interface is 50V, 100mA.
2.9.1.2 Provisionable Items
You can provision several items within the customer-defined alarms. You can provision up to four OC-N facilities for each local orderwire (LOW) and express orderwire (EOW) as orderwire paths. External alarm input contacts on the AIC can be provisioned for type, severity, service affecting status, contact normal, virtual wire, and description. External control output contacts on the AIC can be provisioned for trigger and local description.
The provisionable triggers cause normally open relay contacts to close. The user-provisionable triggers consist of the following:
•
•
•
In addition to provisionable triggers, the CTC allows you to manually force each external output contact to open or close. Manual operation takes precedence over any provisioned triggers that might be present.
2.9.2 Orderwire
Orderwire allows a craftsperson to plug a phoneset into an ONS 15454 and communicate with craftspeople working at other ONS 15454s. The orderwire is a pulse code modulation (PCM) encoded voice channel that uses E1 or E2 bytes in section/line overhead.
The AIC allows simultaneous use of both local (section overhead signal) and express (line overhead channel) orderwire channels on a SONET ring or particular optics facility. Local orderwire also allows communication at regeneration sites when the regenerator is not a Cisco device.
You can provision orderwire functions with the CTC. This is similar to the current provisioning model for DCC channels. In CTC you provision the orderwire communications network during ring turn-up so that all NEs on the ring can reach one another. Orderwire terminations (i.e. the optics facilities that receive and process the orderwire channels) are provisionable. Both express and local orderwire can be configured as on or off on a particular SONET facility. The system supports up to 4 orderwire channel terminations per shelf. This allows linear, single ring, dual ring, and small hub-and-spoke configurations. Keep in mind that orderwire is not protected in ring topologies such as BLSR and UPSR.
Caution
The ONS 15454 implementation of both local and express orderwire is broadcast in nature. The line acts as a party line. There is no signalling for private point-to-point connections. Anyone who picks up the orderwire channel can communicate with all other participants on the connected orderwire subnetwork. The local orderwire party line is separate from the express orderwire party line. Up to four OC-N facilities for each local and express orderwire are provisionable as orderwire paths. The AIC supports a "call" button on the module front panel which, when pressed, causes all ONS 15454 AICs on the orderwire subnetwork to "ring." The ringer/buzzer resides on the AIC. There is also a "ring" LED that mimics the AIC ringer. It flashes when any "call" button is pressed on the orderwire subnetwork. The "call" button and ringer/LED allow a remote craftsperson to get the attention of the craftspeople across the network.
When provisioning the orderwire subnetwork, make sure that an orderwire loop does not exist. Loops cause oscillation and an unusable orderwire channel.

The EC1-12 card provides 12 Telcordia-compliant, GR-253 STS-1 electrical interfaces per card. Each interface operates at 51.840 Mbps over a single 75 ohm 728A or equivalent coaxial span. Figure 2-14 shows the EC1-12 faceplate and Figure 2-15 shows a diagram of the card.
Figure 2-14 EC1-12 Faceplate
STS path selection for UNEQ-P, AIS-P, UPSR using BER thresholds, etc. is done on the SONET ring interfaces in conjunction with the STS cross-connect. The EC1-12 terminates the twelve selected working STS-1 signals from the backplane. The EC1-12 maps each of the twelve received EC1 signals into 12 STS-1s with visibility into the SONET path overhead.
You can install the EC1-12 card in any ONS 15454 multispeed or high-speed card slot. Each EC1-12 interface features DSX-level outputs supporting distances up to 450 feet depending on facility conditions.
An EC1-12 card can be 1:1 protected with another EC1-12 card but cannot protect more than one EC1-12 card. It must be installed in an even-numbered slot to serve as a working card and an odd- numbered slot to serve as a protect card.
2.10.1 EC1-12 Card-Level Indicators
The EC1-12 card faceplate has three card-level LEDs. The red FAIL LED signifies a hardware problem on the EC1-12 card. Replace the unit if the FAIL LED persists. The green ACT LED means that the EC1-12 card is operational and ready to carry traffic. The yellow SF LED indicates a signal failure or condition such as loss of signal (LOS), loss of frame (LOF), or high bit error rate (BER) on one or more of the card's EC1-12 ports.
2.10.2 EC1-12 Port-Level Indicators
You can obtain the status of the EC1-12 card ports using the LCD screen on the fan tray assembly of the ONS 15454 shelf. Use the LCD to access quickly the status of any port or card slot; the screen displays the number and severity of alarms for a given port or slot.

2.22 OC48 ELR DWDM Cards
18 distinct OC-48 ITU 200GHz dense wavelength division multiplexing (DWDM) cards provide the ONS 15454 DWDM channel plan. Each OC48 DWDM card provides one Telcordia-compliant, GR-253 SONET OC-48 interface. The interface operates at 2.48 Gbps over a single-mode fiber span and carries both concatenated and non-concatenated payloads on an STS-1 or VT basis. shows the OC48 ELR faceplate and shows a block diagram of the card.
Figure 2-38 OC48 ELR DWDM Card Faceplate
Nine of the cards operate in the blue band with spacing of 200 GHz on the ITU grid (1530.33 nm, 1531.90 nm, 1533.47 nm, 1535.04 nm, 1536.61 nm, 1538.19 nm, 1539.77 nm, 1541.35 nm, 1542.94 nm), while the other nine operate in the red band with spacing of 200 GHz on the ITU grid
(1547.72 nm, 1549.32 nm, 1550.92 nm, 1552.52 nm, 1554.13 nm, 1555.75 nm, 1557.36 nm, 1558.98 nm, 1560.61 nm).You can install the OC48 ELR cards in any ONS 15454 high-speed slot. You can provision the OC48 ELR cards as part of a BLSR or UPSR or, in an ADM/TM configuration, as either an access tributary or a transport span interface.
Each OC48 DWDM card uses extended long reach optics operating individually within the ITU-T 200 GHz grid. The OC48 DWDM cards are intended to be used in applications with very long unregenerated spans of up to 200 km (with mid-span amplification). These transmission distances are achieved through the use of inexpensive optical amplifiers (flat gain amplifiers) such as erbium doped fiber amplifiers (EDFAs). Using co-located amplification, distances up to 200 km can be achieved for a single channel (160 km for 8 channels). Maximum system reach in filterless applications without the use of optical amplifiers or regenerators is 24 dB or approximately 80 km, depending on the condition of the facilities, number of splices and connectors, or other performance-affecting factors. The OC48 DWDM cards feature wavelength stability of +/- 0.25 nm. Each interface contains a transmitter and receiver.
The OC48 DWDM cards are the first in a family of cards meant to support extended long reach applications in conjunction with optical amplification. Using electro-absorption technology, the OC48 DWDM cards provide a solution at the lower-extended long reach distances.
The OC48 LR 1550 interface features a 1550 nm laser and contains a transmit and receive connector (labeled) on the card faceplate. The OC48 LR 1550 card uses SC connectors, and it supports 1+1 unidirectional protection and provisionable bidirectional and unidirectional switching.
The OC48 ELR cards detect LOS, LOF, LOP, AIS-L, and RDI-L conditions (see Chapter 9, "CTC Alarms," for a description of these conditions). The cards also count section and line BIT errors.
To enable APS, the OC48 ELR cards extract the K1 and K2 bytes from the SONET overhead and process them to switch accordingly. The DCC bytes are forwarded to the TCC.

The E1000-2 Gigabit Ethernet card provides high-throughput, low-latency packet switching of Ethernet encapsulated traffic (IP and other layer 3 protocols) across a SDH/SONET network while providing a greater degree of reliability through SONET "self-healing" protection services. This enables network operators to provide multiple 1000 Mbps access drops for high-capacity customer LAN interconnects, Internet traffic, and cable modem traffic aggregation. Efficient transport and co-existence of traditional TDM traffic with packet-switched data traffic is provided.
The E1000-2 card eliminates the need for external aggregation equipment such as routers, Ethernet or ATM switches at the customer site, remote headends, or distributed POPs.
Each E1000-2 card supports standards-based, layer 2+ Ethernet switching between its Ethernet interfaces and any other Ethernet or SONET trunk interfaces on the ONS 15454. 802.1q tag and port-based VLANS are supported in order to logically isolate traffic (typically subscribers). 802.1p priority is also supported in order to provide multiple classes of service.
You can install the E1000-2 card into any general-purpose slot in the shelf assembly for a total shelf capacity of 20 Gigabit Ethernet ports. Multiple Ethernet cards installed in an ONS 15454 can act as either a single switching entity or as a single switch supporting a variety of SONET port configurations. You can create logical SONET ports by provisioning a number of STS channels to the packet switch entity within the Cisco ADM. Logical ports can be created with a bandwidth granularity of STS 1. In a single or multicard configuration, the ONS 15454 can support the following unstitched STS configurations: 1 STS-12c, 2 STS-6c, 4 STS-3c, or 12 STS-1 and the following stitched configurations: 2 STS-6c, 4 STS-3c, or 12 STS-1s.
2.24.1 E1000-2 Card-Level Indicators
The E1000-2 card faceplate has two card-level LED indicators. The red FAIL LED indicates a hardware problem or catastrophic software failure on the E1000-2 card. As part of the boot sequence, the FAIL LED is turned on until the software deems the card operational. A green ACT LED provides the operational status of the E1000-2. When the ACT LED is green it indicates that the E1000-2 card is active and the software is operational.
2.24.2 E1000-2 Port-Level Indicators
The E1000-2 card also has one bi-color LED per port. The green LINK LED indicates whether linkbeat has been detected (ON), meaning that an active network cable is installed, or if an active network cable is not plugged into the port (OFF). The amber port ACT LED flashes at a rate proportional to the level of traffic being received and transmitted over the port.
