2.1 Overview

The Cisco ONS 15327 uses common control cards, mechanical interface cards, optical cards, and an Ethernet/fast Ethernet card. This overview provides a summary of the cards. Figure 2-1 shows the ONS 15327 slot assignments.

Figure 2-1 ONS 15327 Slot Assignments

2.1.1 Common Control Cards

The two common control cards are the XTC-28-3 card and the XTC-14 card. Both cards provide timing, control, and digital cross-connect functions. They also provide the EIA/TIA-232 DB9 TL1 connection and RJ-45 LAN connection. The XTC-28-3 provides electrical-tributary circuitry for 28 DS-1s and three DS-3s. The XTC-14 provides electrical-tributary circuitry for 14 DS-1s.

2.1.2 Mechanical Interface Cards

The MICs provide the physical connection points for the DS-1 and DS-3 interfaces on the XTC cards, the redundant power inputs, the alarm inputs and outputs, and the building integrated timing supply (BITS) inputs and outputs.

2.1.3 Optical Cards

The optical cards include the OC3 IR 4 1310, the OC12 IR 1310, the OC12 LR 1550, the OC48 IR 1310, and the OC48 LR 1550. The OC3 IR 4 1310 card provides four intermediate-reach OC-3 interfaces. The OC12 IR 1310 card provides one intermediate- or short-reach OC-12 interface, and the OC12 LR 1550 provides one long-reach OC-12 interface. The OC48 IR 1310 card provides one intermediate-reach OC-48 interface and the OC48 LR 1550 provides one long-reach OC-48 interface.

2.1.4 Ethernet Card

The Ethernet card provides four Layer 2 switched, autosensing, 10/100BaseT Ethernet interfaces. Each interface supports full-duplex operation for a maximum bandwidth of 200 Mbps per port.

2.1.5 Gigabit Ethernet Card

The Gigabit Ethernet card provides two 1000-Mbps Gigabit Ethernet interfaces. Each interface supports full-duplex operation for a maximum bandwidth of 2000 Mbps per port.

2.2 XTC Cards

This section describes the features and functions of the XTC cards. The ONS 15327 has two XTC cards, the XTC-28-3 and the XTC-14 card.

2.2.1 XTC Card Description

The XTC cards perform system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection and resolution, SONET DCC (data communication channel) termination, system fault detection, and cross-connect maintenance and management for the ONS 15327. The XTC cards also provide the circuitry for the DS-1 and DS-3 interfaces and ensure that the system maintains Telcordia timing requirements.

An XTC card is required to operate the ONS 15327 and can be used in a redundant or nonredundant configuration. Figure 2-2 shows the XTC-28-3 faceplate.


Note You can connect to either the active or standby XTC using the LAN or CRAFT port, but you cannot connect to both cards simultaneously. Connecting to both the active and standby XTC at the same time results in a loss of connectivity.


Figure 2-2 XTC-28-3 Card Faceplate

Figure 2-3 shows the XTC-14 faceplate.

Figure 2-3 XTC-14 Card Faceplate

2.2.1.1 XTC Front Panel

The XTC cards have an alarm cutoff (ACO) button, an RJ-45 LAN port, an EIA/TIA-232 TL1 (CRAFT) interface port, and a LAMP TEST button. The XTC-28-3 front panel has 12 LEDs, and the XTC-14 front panel has 11. The following list describes each LED:

The red FAIL LED indicates an XTC hardware problem. Replace the card if the FAIL LED persists.

The ACT/STBY (Active/Standby) LED indicates whether the XTC is active and providing timing reference and shelf control (green), or is in standby to the active XTC (amber).

The green SYNC LED illuminates when the active XTC qualifies a timing reference from the optical facility or an external BITS input.

The ACO LED indicates that the ACO function has been activated. To activate the ACO, press the ACO button on the front panel.

The DS3 SF LED (XTC-28-3 only) indicates a signal fail with one or more of the DS-3 interfaces.

The DS1 SF LED indicates a signal fail with one or more of the DS-1 interfaces.

The green PWR A and PWR B LEDs illuminate when adequate power voltage is being received by the PWR A and PWR B connections on the MIC cards.

The CRIT LED illuminates when a critical alarm is present.

The MAJ LED illuminates when a major alarm is present.

The MIN LED illuminates when a minor alarm is present.

The red REM LED illuminates when a remote alarm is present in one or several of the remote terminals, or if an external alarm or condition is present.

2.2.1.2 Support for DS-1 and DS-3

The XTC cards contain the circuitry for connecting DS-1s. The XTC-28-3 also contains the circuitry for connecting DS-3s. The XTC-28-3 supports 28 DS-1s and 3 DS-3s. The XTC-14 supports 14 DS-1s. The DS-1 circuitry on the XTC cards maps each of the received DS-1 signals into VT 1.5s and concatenates these virtual tributaries (VTs) into one STS-1. Full VT 1.5 grooming is supported.

The physical connection points are located on the MIC cards. See the "MIC Description" section for more information about physical connections.

2.2.1.3 XTC Timing and Control Functionality

The XTC cards combine the timing and control functions into one card. You can install the XTC cards in one or both of the control slots (Slots 5 and 6). XTC cards must be installed in both of the control slots for redundancy. In a nonredundant configuration, you must install the XTC in Slot 6.

The XTC cards support multichannel, high-level data link control (HDLC) processing for the DCC. Up to four DCCs can be routed over the serial communication interface (SCI) and terminated at the XTC card. The XTC cards process ten DCCs to enable remote system management interfaces.


Note ONS 15327 Releases 3.3 and later support DCC tunneling of non-Cisco equipment.


The node database, IP address, and system software are stored in XTC card nonvolatile memory, which allows quick recovery in the event of a power or card failure.

The XTC cards perform all system-timing functions for each ONS 15327. The XTC cards select a recovered clock from optical line cards, a building integrated timing supply (BITS), or an internal Stratum 3 reference as the system-timing reference. You can provision any of the clock inputs as a primary or secondary timing source. A slow-reference tracking loop allows the XTC cards to synchronize to the recovered clock, which provides holdover if the reference is lost.

In a redundant configuration, if the working XTC card fails, traffic switches to the protect XTC card. All XTC protection switches conform to protection switching standards when the bit error rate (BER) counts are not in excess of 1 E-3 and completion time is less than 50 ms.

The XTC cards feature an RJ-45 10BaseT LAN port and an EIA/TIA-232 DB9 type craft interface for user interfaces. The craft port runs at 9600 bps.

2.2.1.4 XTC Cross-Connect Functionality

The XTC card is the central element for ONS 15327 switching. It establishes cross connections and performs time-division switching (TDS) at the STS-1 and VT 1.5 level between ONS 15327 traffic cards.

The switch matrix on the XTC card consists of 288 bidirectional 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 nonblocking 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 2-4 shows the cross-connect matrix for the XTC card.

Figure 2-4 Cross-Connect Matrix

The XTC card supports a total of 672 cross-connects with a payload granularity of VT 1.5. The VT functionality supports ring configurations with a mix of VT-capable Cisco transport network elements (NEs) and STS-only capable Cisco transport NEs.

The XTC card provides protection switching control for external and internal VT paths. The card also performs path- and STS-level monitoring and protection switching.

2.2.2 VT Mapping

The Cisco ONS 15327 performs VT mapping according to Telcordia GR-253 standards. Table 2-1 shows the VT numbering scheme for the ONS 15327 as it relates to the Telcordia standard.

2.3 Mechanical Interface Cards

This section describes the features and functions of the MICs.

2.3.1 MIC Description

Two MIC cards (MIC A and MIC B) are required to operate the Cisco ONS 15327 if you are using XTC-28-3 cards and/or you need redundant power inputs. The MICs provide power connection points, physical interfaces for DS-1s and DS-3s, and external timing and alarm interfaces.

Figure 2-6 shows the MIC A faceplate. MIC A is keyed so that it can only be installed in Slot 8.

Figure 2-6 MIC A Card Faceplate

Figure 2-7 shows the MIC-28-3-B faceplate. MIC-B is keyed so that it can only be installed in Slot 7.

Figure 2-7 MIC B Card Faceplate

2.3.1.1 DS-1 Physical Interface

Each MIC uses a 64-pin Champ connector to provide 14 DS-1 interfaces. MIC-28-3-A provides connection to DS-1s 1 to 14, and MIC-28-3-B provides connection to DS-1s 15 to 28. The XTC cards house the electrical tributary circuitry for managing the individual DS-1s.

2.3.1.2 DS-3 Physical Interface

Because transmit (out) and receive (in) interfaces are on different cards, you must install both MICs to use the DS-3 capabilities of the ONS 15327. The DS-3 interfaces use BNC connectors. MIC-28-3-A provides the three transmit (Tx) interfaces and MIC-28-3-B provides the three receive (Rx) interfaces. The XTC-28-3 card houses the electrical-tributary circuitry for managing DS-3s.

2.3.1.3 Power Connection

Each MIC has one -48 VDC power terminal that uses spring terminal block connectors and accepts #12 to #16 AWG wire (the National Electrical Code [NEC] requires #12 to #14 AWG wire). To establish redundant power, install both MICs and connect each one to a power source.

2.3.1.4 External Alarms and Controls

Each MIC has three Form C discrete external alarm inputs and one Form C discrete external control. Connection to the external alarms and controls uses an RJ-45 connector. Two wires of the RJ-45 connector are used for the external control, which defaults to the open position. Six wires of the RJ-45 connector are used for the external alarm input (for additional information, refer to the Cisco ONS 15327 Procedure Guide).

In CTC, you can provision the six external alarm inputs (three on each MIC) and the two external controls (one on each MIC). External alarm inputs are typically used for external sensors such as open doors, temperature sensors, flood sensors, and other environmental conditions. They can be set to Alarm on Closure or Alarm on Open. The alarm severity can be set to any of five available levels (Critical, Major, Minor, Not Alarmed, Not Reported). In addition to severity, you can set alarm type and virtual wire for alarm contacts 1 to 4 and define when the alarm is raised. You can assign a 63-character alarm description for display in the alarm log of the CTC. The alarm condition remains until the external input quits driving the contact and you clear the alarm in the CTC. For instructions, refer to the Cisco ONS 15327 Procedure Guide.

External controls 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. 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 15327 alarm condition including the user-defined input alarms, severity-based (for example, trigger when any major alarm occurs) alarms, or remote alarms. CTC provisioning of this alarm-to-output-contact association is menu driven and includes alarms and individual alarms within categories. The output contact electrical interface is 50 V, 100 mA. For procedures that provision external controls, refer to the Cisco ONS 15327 Procedure Guide.

2.3.1.5 BITS Interface

Each MIC provides connection for one BITS clock input and one BITS clock output using an RJ-45 connector. Both use two wires of the RJ-45 connector.

The interface operates at 155.52 Mbps over a single-mode fiber span and supports VT payloads and nonconcatenated or concatenated payloads for STS-1 or STS-3c. Figure 2-8 shows the OC3 IR 4 1310 faceplate.

Figure 2-8 OC3 IR 4 1310 Card Faceplate

You can install the OC3 IR 4 1310 card in any ONS 15327 high-speed card slot. The card can be provisioned as part of a UPSR or a linear add-drop multiplexer (ADM) configuration.The card does not support BLSR. Each port features a 1310 nm laser and contains a transmit and receive connector (labeled, the left-hand connector is the transmit [Tx] port and the right-hand connector is the receive [Rx] port) on the card faceplate. The card uses LC connectors.

The OC3 IR 4 1310 card supports 1+1 unidirectional or bidirectional protection switching. You can provision protection on a per-port basis. See the "Optical Card Protection" section on page 3-2 for more information.

The OC3 IR 4 1310 detects loss of signal (LOS), loss of frame (LOF), loss of pointer (LOP), line alarm indication signal (AIS-L), and line remote defect indication (RDI-L) conditions. Refer to the Cisco ONS 15327 Troubleshooting Guide for a description of these conditions. The card also counts section and line bit interleaved parity (BIP) errors.

2.4.2 OC3 IR 4 1310 Card-Level Indicators

2.9 E10/100-4 Card

This section describes the features and functions of the ONS 15327 Ethernet card, called the E10/100-4 card. For card provisioning, refer to the Cisco ONS 15327 Procedure Guide.

2.9.1 E10/100-4 Card Description

The E10/100-4 card provides four IEEE 802.3-compliant, 10/100 interfaces. Each interface supports full-duplex operation for a maximum bandwidth of 200 Mbps per port and 622 Mbps per card. Each port can independently detect the speed of an attached device (autosenses) and automatically connects at the appropriate speed. The ports autoconfigure to operate at either half or full duplex and can determine whether to enable or disable flow control. You can manually set the port speed and duplex mode. The card faceplate and block diagram are shown in Figure 2-18 and Figure 2-19.

Figure 2-18 E10/100-4 Card Faceplate

Figure 2-19 E10/100-4 Block Diagram

The E10/100-4 Ethernet card provides high-throughput, low-latency packet switching of Ethernet traffic across a SONET network while providing a greater degree of reliability through SONET "self-healing" protection services. This Ethernet capability enables network operators to provide multiple 10/100 Mbps access drops for high-capacity customer LAN interconnects, Internet traffic, and cable modem traffic aggregation. Efficient transport and coexistence of traditional TDM traffic with packet-switched data traffic is provided.

Each E10/100-4 card supports standards-based, wire-speed, Layer 2, Ethernet switching between its Ethernet interfaces. IEEE 802.1Q-tag and port-based VLANs are supported in order to logically isolate traffic (typically subscribers). Priority queuing is also supported in order to provide multiple classes of service.

You can install the E10/100-4 card in any high-speed slot. Multiple Ethernet cards installed in an ONS 15327 can act as a single switch or multiple switches supporting a variety of SONET port configurations. To create logical SONET ports, provision a number of STS channels to the packet switch entity within the ADM. You can create logical ports with a bandwidth granularity of STS-1. The ONS 15327 can support six STS-1s, two STS-3cs, one STS-6c, or one STS-12c in single-card EtherSwitch mode. It supports three STS-1s or one STS-3c in multicard EtherSwitch mode.

2.9.2 E10/100-4 Card-Level Indicators

The E10/100-4 card faceplate has two card-level LED indicators ( Table 2-7).

Table 2-7 E10/100-4 Card-Level Indicators

2.10  G1000-2 Card

This section describes the features and functions of the ONS 15327 Gigabit Ethernet card, called the G1000-2 card. For card provisioning, refer to the Cisco ONS 15327 Procedure Guide.

2.10.1  G1000-2 Card Description

The G1000-2 provides two IEEE 802.3-compliant, 1000 Mbps ports for high-capacity customer LAN interconnections. Each port supports full-duplex operation for a maximum bandwidth of 2000 Mbps per port.

The G1000-2 card uses standard Small-Form-Factor Pluggable (SFP) modules for the optical ports. SFPs are input/output devices that plug into a Gigabit Ethernet port to link the port to the fiber-optic network. Cisco provides two SFP modules: one for short-reach applications and one for long-reach applications. The short-reach model connects to multimode fiber and the long-reach model requires single-mode fiber.

Both SFP modules are offered as separate orderable products: an IEEE 1000BaseSX compliant, 85-nm optical module and an IEEE 1000BaseLX-compliant, 1300-nm optical module. The 850-nm SX optics are designed for multimode fiber and distances of up to 220 meters on 62.5 micron fiber and up to 550 meters on 50 micron fiber. The 1300-nm LX optics are designed for single-mode fiber and distances of up to 10 kilometers.

The card faceplate is shown in Figure 2-20.

Figure 2-20 G1000-2 Card Faceplate

The G1000-2 Gigabit Ethernet card provides high-throughput, low latency transport of Ethernet encapsulated traffic (IP and other Layer 2 or Layer 3 protocols) across a SONET network. Carrier-class Ethernet transport is achieved by hitless (< 50 ms) performance in the event of any failures or protection switches (such as 1+1 APS, UPSR, or BLSR). Full provisioning support is possible via CTC, TL1, or CTM.

The circuit sizes supported are STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-24c and STS-48c.

2.10.2  G1000-2 Card-Level Indicators

The G1000-2 card faceplate has two card-level LED indicators ( Table 2-9).
