This chapter describes the Cisco ONS 15454 SDH cards. It includes descriptions, hardware specifications, and block diagrams for each card. For installation and card turn-up procedures, refer to the Cisco ONS 15454 SDH Installation and Operations Guide, R3.3.
The cards for the ONS 15454 SDH include front mount electrical connection cards (FMECs), common control cards, electrical cards, optical cards, and Ethernet cards. Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 SDH shelf assembly. The cards are then installed into slots displaying the same symbols (refer to the Cisco ONS 15454 SDH Installation and Operations Guide, R3.3 for a list of slots/symbols). The overview in this section provides a summary of the cards.
The common control cards are the Timing Communications and Control International (TCC-I) card, and the Cross Connect 10 GBits/s (Gbps) XC10G card. The TCC-I is the main processing center of the ONS 15454 SDH and provides system initialization, provisioning, alarm reporting, maintenance, and diagnostics. The XC10G card is the central element for switching; it establishes connections and performs time division switching (TDS). Power supply and alarming interfaces are dealt with in the Electrical Cards section of this chapter.

Note The ONS 15454 SDH is a flexible metro optical transport system supporting a wide variety of
applications. The power consumption of the shelf assembly varies depending upon shelf
configuration. Your power distribution network can be designed based on your maximum ONS 15454
SDH system power draw, or use the ONS 15454 SDH's maximum rated shelf power draw. If you select to design your power plant to your maximum planned ONS 15454 SDH system configuration, the "Cisco ONS 15454 SDH Troubleshooting and Maintenance Guide, R3.3" lists the power consumption for each card that can be used to determine your maximum ONS 15454 SDH system power draw. The general guideline for fuse selection is 20% above the maximum calculated system power draw. If you design your power system to the ONS 15454 SDH's maximum rated shelf power draw, Cisco recommends that you select a power distribution system supporting a minimum capacity of 30 amps for each A and B power feeder on each ONS 15454 SDH shelf assembly. Feeder lines should be fused at 30 amps. This recommendation is based on the shelf assembly's current rated maximum power draw of 30 amps at -48VDC. The maximum power draw configuration on the ONS 15454 SDH, based on the hardware available with Release 3.3, requires 30 amps at -48VDC. |
The ONS 15454 SDH provides a variety of electrical card protection methods. This section describes the protection options. Figure 3-1 shows a 1:1 protection scheme and Figure 3-2 shows a 1:N protection scheme.
The term 1:0 protection is sometimes used for an unprotected configuration.
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. When the failure on the working card is resolved, traffic automatically reverts to the working card. Figure 3-1 shows the ONS 15454 SDH in a 1:1 protection configuration; Slot 1 is protecting Slot 2, Slot 3 is protecting Slot 4, Slot 17 is protecting Slot 16, and Slot 15 is protecting Slot 14. Each working card is paired with a protect card. Slots 6 and 12 are not used for electrical cards. They have no corresponding FMEC slots.
1:N protection allows a single card to protect several working cards. An E1-N-14 card protects up to four E1-N-14 cards, and a DS3i-N-12 card protects up to four DS3i-N-12 cards.
Currently, 1:N protection operates only at the E-1 and DS-3 levels. The 1:N protect cards must match the levels of their working cards. For example, an E1-N-14 protects only E1-N-14 cards, and a DS3i-N-12 protects only DS3i-N-12 cards.
The physical E-1 or DS-3 ports on the ONS 15454 SDH FMEC cards use the working card until the working card fails. When the node detects this failure, the protection card takes over the physical E-1 or DS-3 electrical interfaces through the relays and signal bridging on the backplane. Figure 3-2 shows the ONS 15454 SDH in a 1:N protection configuration. Each side of the shelf assembly has only one card protecting all of the cards on that side.
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 Cisco Transport Controller (CTC). For instructions, refer to the Cisco ONS 15454 SDH Installation and Operations Guide, R3.3. All cards in a protection group share the same reversion settings. 1:N protection groups default to automatic reversion.
Several rules apply to 1:N protection groups in the ONS 15454 SDH:
The ONS 15454 SDH supports 1:N equipment protection for all add-drop multiplexer configurations (ring, linear, and terminal), as specified by ITU-T G.841.
The ONS 15454 SDH 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.
|
Note For EIA descriptions and installation, refer to Cisco ONS 15454 SDH Installation and Operations Guide, R3.3. |
|
Note When a protection switch moves traffic from the DS3i-N-12 working/active card to the DS3i-N-12 protect/standby card, ports on the new active/standby card cannot be taken out of service. Lost traffic can result when a port is taken out of service even if the DS3i-N-12 active/standby card no longer carries traffic. |
The ONS 15454 SDH currently supports 1+1 span protection to create redundancy for optical cards. 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.
For multiport cards such as the E1-N-14, DS3i-N-12, and the OC3 IR 4/STM1 SH 1310, the ports on the protect card support the corresponding ports on the working card. 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. But the working and protect ports cannot be on the same card. 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 working card) and leave three ports unprotected. Conversely, you could assign three ports as protection ports and leave one port unprotected.
You create and modify protection schemes using CTC software. Refer to the Cisco ONS 15454 SDH Installation and Operations Guide, R3.3.
Unprotected cards are not included in a protection scheme; therefore, a card failure or a signal error results in lost data. An unprotected configuration is sometimes called 1:0 protection. Because no bandwidth is reserved for protection, unprotected schemes maximize the available ONS 15454 SDH bandwidth. Figure 3-3 shows the ONS 15454 SDH in an unprotected configuration. All cards are in a working state.
The TCC-I performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection/resolution, SDH SOH Data Communications Channel (DCC) termination, and system fault detection for the ONS 15454 SDH. The TCC-I also ensures that the system maintains Stratum 3 E (G.813) timing requirements. Figure 3-4 shows the TCC-I faceplate and Figure 3-5 shows a block diagram of the card.
The TCC-I supports multichannel, high-level data link control (HDLC) processing for the DCC. Up to 48 DCCs can be routed over the TCC-I and up to ten DCCs can be terminated at the TCC-I (subject to available optical digital communication channels). The TCC-I selects and processes ten DCCs to facilitate remote system management interfaces.
The TCC-I also originates and terminates a cell bus carried over the module. The cell bus supports links between any two cards in the node, 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-I non-volatile memory, which allows quick recovery in the event of a power or card failure.
The TCC-I performs all system-timing functions for each ONS 15454 SDH. The TCC-I monitors the recovered clocks from each traffic card and two BITS ports for frequency accuracy. The TCC-I selects a recovered clock, a BITS or an internal Stratum 3 E 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-I to synchronize with the recovered clock, which provides holdover if the reference is lost.
Install TCC-I cards in Slots 7 and 11 for redundancy. If the active TCC-I fails, traffic switches to the protect TCC-I. All TCC-I protection switches conform to protection switching standards when the BER counts are not in excess of 1 * 10-3 and completion time is less than 50 ms.
The TCC-I uses a 10Base-T LAN port for user interfaces, being led via the back plane to the port accessible on the front of the MIC-C/T/P FMEC.
|
Note Cisco does not support operating the ONS 15454 SDH with only one TCC-I card. For full functionality and to safeguard your system, always operate in a redundant configuration. |
|
Note CTC software does not monitor for the presence or absence of FMECs unless the TCC-I(s) card has reached the active/standby state. During transitional states such as power-up or TCC-I reset CTC ignores the FMEC inventory displayed in node view. |
|
Note When a second TCC-I card is inserted into a node, it synchronizes its software, its backup software, and its database with the active TCC-I. If the software version of the new TCC-I does not match the version on the active TCC-I, the newly inserted TCC-I copies from the active TCC-I, taking about 15 to 20 minutes to complete. If the backup software version on the new TCC-I does not match the version on the active TCC-I, the newly inserted TCC-I copies the backup software from the active TCC-I, again, taking about 15 to 20 minutes. Copying the database from the active TCC-I takes about 3 minutes. Depending on the software version and backup version the new TCC-I started with, the entire process can take between 3 and 40 minutes. |
The TCC-I faceplate has eight LEDs. The first two LEDs are card-level indicators.

The XC10G card cross-connects STM-1, STM-4, STM-16, and STM-64 signal rates. The XC10G provides a maximum of 384 x 384 VC-4 non-blocking cross connections. Any STM-1 on any port can be connected to any other port, meaning that the STM cross connections are non blocking.
The XC10G faceplate, cross-connections, and functions are shown in Figure 3-6, Figure 3-7, and Figure 3-8.
|
Note The lowest level cross-connect is STM-1. Lower level signals, such as E-1, DS-3, or E-3, can be dropped. This may leave part of the bandwidth unused. |
The XC10G card manages up to 192 bidirectional STM-1 cross-connects. The TCC-I assigns bandwidth to each slot on a per STM-1 basis. The XC10G card works with the TCC-I card to maintain connections and set up cross-connects within the system. The XC10G is required to operate the ONS 15454 SDH. You can establish cross connect and provisioning information through the Cisco Transport Controller (CTC). The TCC-I establishes the proper internal cross connect information and sends the setup information to the XC10G cross connect card.
|
Note Cisco does not recommend nor support operating the ONS 15454 SDH with only one XC10G card. To safeguard your system, always operate in a redundant configuration. |
The XC10G faceplate has two card-level LEDs.

The fourteen-port ONS 15454 SDH E1-N-14 card provides fourteen ITU-compliant, G.703 E-1 ports. Each port of the E1-N-14 card operates at 2.048 MBits/s (Mbps) over a 120W twisted-pair copper cable (with FMEC-DS1/E1) or over a 75W unbalanced coaxial cable (with FMEC-E1). Figure 3-9 shows the E1-N-14 faceplate and Figure 3-10 shows a block diagram of the card.
Each E1-N-14 port features ITU-T G.703 compliant level outputs and inputs supporting cable losses of up to 6 dB at 1024 kHz. The E1-N-14 card supports 1:N (N £ 4) protection. You can also provision the E1-N-14 to monitor line and frame errors in both directions.
The E1-N-14 card can function as a working or protect card in 1:1 or 1:N protection schemes. If you use the E1-N-14 as a standard E-1 card in a 1:1 protection group, you can install the E1-N-14 card in any multispeed or high-speed card slot on the ONS 15454 SDH. If you use the card's 1:N functionality, you must install an E1-N-14 card in Slot 3 (for bank A) or Slot 15 (for bank B).
You can group and map E1-N-14 card traffic in VC-12 as per ITU-T G.707 to any other card in an ONS 15454 SDH node. For performance-monitoring purposes, you can gather bidirectional E-1 frame-level information (loss of frame, parity errors or CRC errors, for example).
|
Note The lowest level cross-connect is STM-1. Lower level signals, such as E-1, DS-3, or E-3, can be dropped. This may leave part of the bandwidth unused. |

The twelve-port ONS 15454 SDH DS3i-N-12 card provides twelve ITU-T G.703, GR-499, ITU-T G.704 compliant DS-3 ports per card. Each port operates at 44.736 MBits/s (Mbps) over a 75W coaxial cable (with FMEC-E3/DS3). The DS3i-N-12 can detect several different errored logic bits within a DS-3 frame. This function lets the ONS 15454 SDH identify a degrading DS-3 facility caused by upstream electronics (DS-3 Framer). In addition, DS3 frame format auto detection and J1 path trace are supported. By monitoring additional overhead in the DS-3 frame, subtle network degradations can be detected. Figure 3-13 shows the DS3i-N-12 faceplate and Figure 3-14 shows a block diagram of the card.
The following list summarizes the DS3i-N-12 card features:

Each OC48 ELR/STM16 EH 100 GHz card uses extended long reach optics operating individually within the ITU 100 GHz grid. The OC48 ELR/STM16 EH 100 GHz cards are intended to be used in applications with 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 is 24 dB or approximately 80 km without the use of optical amplifiers or regenerators. However, system reach also depends on the condition of the facilities, number of splices and connectors, and other performance-affecting factors. The OC48 ELR/STM16 EH 100 GHz cards feature wavelength stability of + 0.25 nm. Each port contains a transmitter and a receiver.
The OC48 ELR/STM16 EH 100 GHz cards are the first in a family of cards meant to support extended long reach applications in conjunction with optical amplification. Using Distributed Feedback (DFB) Laser technology, the OC48 ELR/STM16 EH 100 GHz cards provide a solution at the lower-extended long reach distances.
The OC48 ELR/STM16 EH 100 GHz port features a 1550 nm range laser and contains a transmit and receive connector (labeled) on the card faceplate. The card uses SC connectors and supports 1+1 unidirectional and bidirectional protection switching.

The E100T-G card provides twelve ports of IEEE 802.3-compliant, 10/100 interfaces. Each interface supports full-duplex operation for a maximum bandwidth of 200 MBits/s (Mbps) per port and 2.488 GBits/s (Gbps) per card. Each port independently detects the speed of an attached device (auto-senses) and automatically connects at the appropriate speed. The ports auto-configure to operate at either half or full duplex and can determine whether to enable or disable flow control. Figure 3-43 shows the card faceplate and Figure 3-44 shows a block diagram of the card.
The E100T-G Ethernet card provides high-throughput, low-latency packet switching of Ethernet traffic across an SDH/SONET network while providing a greater degree of reliability through SDH/SONET "self-healing" protection services.
