Note
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.
This chapter describes the Cisco ONS 15327 cards. It includes descriptions, hardware specifications, and block diagrams for each card. For installation and turn-up procedures, refer to the Cisco ONS 15327 Procedure Guide.
Chapter topics include:

Figure 2-1 ONS 15327 Slot Assignments
2.1.1 Card Compatibility
This section lists ONS 15327 cards and their compatible software versions. In the table below, "Yes" means the cards are compatible with the listed software version. Table cells with dashes mean cards are not compatible with the listed software versions.
Table 2-1 lists Cisco Transport Controller (CTC) software release compatibility for each card.
2.1.2 Common Control Cards
The two common control cards are the Cross-Connect, Timing, and Control (XTC-28-3 and XTC-14) cards. 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.
2.1.3 Mechanical Interface Cards
The mechanical interface cards (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.

2.1.5 E10/100-4 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.
2.1.6 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 (XTC-28-3/XTC-14)
This section describes the features and functions of the XTC cards.
2.2.1 XTC Card Overview
The XTC cards perform system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection and resolution, SONET data communication channel (DCC) 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

2.2.3 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 VT1.5 grooming is supported.
The physical connection points are located on the MIC. See the "MIC Overview" section for more information about physical connections.
2.2.4 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 common control slots (Slots 5 and 6). XTC cards must be installed in both of the common 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
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 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.
2.2.5 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.
2.2.6 VT Mapping
The Cisco ONS 15327 performs VT mapping according to Telcordia GR-253 standards. Table 2-2 shows the VT numbering scheme for the ONS 15327 as it relates to the Telcordia standard.
Figure 2-5 shows the block diagram for the XTC card.

2.3 Mechanical Interface Cards
This section describes the features and functions of the MICs.
2.3.1 MIC Overview
Two MICs (MIC A and MIC B) are required to operate the Cisco ONS 15327 when using XTC-28-3 cards or when redundant power inputs are needed. 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 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 Faceplate
2.3.2 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.
2.3.3 DS-3 Physical Interface
Because the 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.
2.3.4 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.
2.3.5 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.
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 raised 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 alarms (for example, trigger when any major alarm occurs), 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. To provision external controls, refer to the Cisco ONS 15327 Procedure Guide.
2.3.6 BITS Interface
Each MIC provides connection for one BITS clock input and one BITS clock output using an RJ-45 connector. Each MIC uses two wires of the RJ-45 connector.

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.

Figure 2-20 shows the card faceplate.
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, path protection, or BLSR) and software upgrades. Full provisioning support is possible via CTC, TL1, or CTM (refer to the Cisco ONS 15454 and Cisco ONS 15327 TL1 Command Guide for G-Series TL1 provisioning commands).
The card also features SONET-style alarms support, Ethernet PM and RMON functions, and serviceability options including enhanced port states, terminal and facility loopbacks on OC-N circuit paths, and J1 path trace. For additional information about terminal and facility loopbacks, refer to the Cisco ONS 15327 Troubleshooting Guide.
2.10.2 SFPs
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 (721.8 feet) on 62.5 micron fiber and up to 550 meters (1,804.5 feet) on 50 micron fiber. The 1300-nm LX optics are designed for single-mode fiber and distances of up to 10 kilometers (6.2 miles).
See the "SFP Specifications" section for more information.
