This chapter describes the Cisco 6732 full access device chassis, and the service modules and line interface modules supported by the Cisco 6732 full access device. This chapter includes the following sections:
The Cisco 6732 full access device multiport-per-slot architecture supports fundamental time division mutliplexing (TDM) and asynchronous transfer mode (ATM) technologies. The Cisco 6732 is compliant with relevant NEBS, ANSI, and Telcordia network element standards. The Cisco 6732 provides the following functionality and services for central office terminal (COT) and large remote terminal (RT) applications:
The Cisco 6732 chassis is designed for mounting in 19-inch or 23-inch equipment racks. It is a dual-shelf chassis that holds the following:
The first three slots on the left of each shelf are exclusively designed to support the following Cisco 6732 service modules:
Each shelf of the Cisco 6732 provides 16 numbered general-purpose slots for use with line interface modules and selected service modules. The first two general purpose slots on the top shelf support the following service modules, in addition to all line interface modules:
The backplane provides the basic architecture and interconnectivity of the Cisco 6732 full access device. The backplane provides all cabling for the Cisco 6732, except for line interface modules with front panel connectors such as the DSX3/CHNL, STSX/CHNL, OC3c-UNI, and T1-2-V35 modules.
Service modules for the Cisco 6732 full access device are hot swappable. They can be inserted into (or removed from) the Cisco 6732 chassis with or without power applied to the system without incurring damage.
The following service modules are available for the Cisco 6732 full access device:
The BPS-HP module must be placed in designated-purpose slots BPS-A or BPS-B.
The LEDs on the BPS-HP module indicate chassis and module status. (See Table 1-1.)
| LED | Status | Condition |
FAIL | Red Off | BPS has failed. BPS has not failed. |
ACTV | Green Off | BPS is powering the active MCC. BPS is not powering an MCC. |
PWR | Green Off | BPS is supplying bus voltage above the minimum threshold of -42.5 VDC. BPS is not supplying voltage. |
FUSE | Red Off | A non-replaceable fuse has blown. No fuses have blown. |
The BPS-HP module does not have any external connectors or interfaces.
Protected (redundant) systems require two BPS-HP modules. One BPS-HP module is inserted in slot BPS-A (to power the service modules in the top shelf) and one in slot BPS-B (to power the service modules in the bottom shelf). If the active BPS-HP module fails, the system switches over to the shelf containing the standby BPS-HP module.
The stratum 3 clock on the main control card (MCC-STR3) module supports synchronization and holdover requirements for the stratum level 3. Systems can also derive timing from an inbound transport span such as a T1, DSX1, or STSX-1.
The MCC-STR3 module supports the following functions:
The MCC-STR3 module must be placed in designated-purpose slots MCC-A or MCC-B.
