This chapter describes the 16-port OC-3c interface module that is supported in the
Catalyst 8540 MSR. This chapter includes the following sections:
The Catalyst 8540 MSR supports up to eight OC-3c interface modules with a maximum of 128 OC-3c interface ports.
 |
Note The Catalyst 8510 MSR, Catalyst 5500, and LightStream 1010 do not support the 16-port OC-3c interface module. |
Figure 5-1 shows a 16-port OC-3c multimode interface module.
The 16-port OC-3c multimode interface module provides short-reach intercampus and WAN ATM connections up to 500 m. (See Figure 5-2.)
The OC-3c port adapter with multimode and single-mode connections meets the Japan Approvals Institute for Telecommunications Equipment (JATE) approval. See Table 5-1 for JATE approval details for the OC-3 port adapter.

This section describes supported cabling configurations for the OC-3c interface module, which provides multimode connections.
|
Note All ATM interfaces are full duplex. You must use the appropriate ATM interface cable to connect the ATM multimode interface with an external ATM network. |
The OC-3c interface module provides an interface to ATM switching fabrics for transmitting and receiving data bidirectionally at up to 155 Mbps. The OC-3c interface module can support interfaces that connect to the OC-3c multimode fiber-optic--STS-3c/STM-1 physical layer.
|
Note For descriptions of ATM cabling requirements, see the "ATM Connection Equipment Requirements" section. |
To connect the OC-3c interface module to the external ATM switch, use MT-RJ connectors. See Figure 5-3 for multimode fiber-optic connections with MT-RJ connectors.
|
Note For a description of the MT-RJ connector, see the "ATM Connection Equipment Requirements" section. (See Figure 2-2.) |
The LEDs provide status information for the individual OC-3c multimode interface connections. The LEDs are shown in Figure 5-3 and described in Table 5-2.
| LED | State | Description |
|---|---|---|
Off | Carrier detect signal not received | |
Off | Administratively down or LOS1 | |
Off | No transmit line activity and administratively down |
| 1LOS = loss of signal 2LOF = loss of frame 3OCD = out of cell delineation 4AIS = alarm indication signal 5LOP = loss of pointer 6RDI = remote defect indicator |
