  • Line Interface Modules

Overview

The Cisco 6705 integrated access device multiport-per-slot architecture supports fundamental time division mutliplexing (TDM) and asynchronous transfer mode (ATM) technologies. The Cisco 6705 integrated access device is compliant with relevant NEBS, ANSI, and Telcordia network element standards. The Cisco 6705 provides the following functionality for customer premises equipment (CPE) and remote terminal (RT) applications:

• Digital loop carrier (DLC)

• Integrated access

Components and Features

Chassis

The Cisco 6705 integrated access device contains a single shelf chassis that holds the following:

• Designated-Purpose Slots

• General-Purpose Slots

• Backplane

Designated-Purpose Slots

The first two slots at the left of the Cisco 6705 chassis are exclusively designed to support the following service modules:

• The slot labeled BPS exclusively supports the bank power supply (BPS-AC) module, which provides power to the MCC-INT module and passes -48 VDC to the line interface modules.

• The slot labeled MCC exclusively supports the main control card (MCC-INT) module, which provides centralized processing, synchronization, and some switching functions. The MCC module provides Ethernet 10BaseT connectivity.

General-Purpose Slots

The Cisco 6705 chassis provides five numbered general-purpose slots designed to support the following line interface service modules:

• General-purpose slot number 1, to the immediate right of the MCC slot, supports only the RPOTS/16, FXS/16, and RUVG/8 line interface modules, and the BRG service modules.

• Slots 2 through 5 support all line interface modules and the BRG service module.

Backplane

The backplane provides the basic architecture and interconnectivity of the Cisco 6705 integrated access device. The backplane also offers three connectors for subscriber cabling. For more information about cabling, see "Cabling and Wiring."

Service Modules

Service modules for the Cisco 6705 integrated access device are hot swappable. They can be inserted into (or removed from) the Cisco 6705 chassis with or without power applied to the system without incurring damage.

The following service modules are available for the Cisco 6705 integrated access device:

• Bank Power Supply, Alternating Current

• Main Control Card, Integrated

• Bank Ring Generator

Bank Power Supply, Alternating Current

The bank power supply, alternating current (BPS-AC) module supplies power to the MCC-INT module and passes -48 VDC to the line interface modules. The BPS-AC derives the -48 VDC from an internal AC/DC converter that accepts 120 VAC and converts it to the -48 VDC needed for the telephony equipment. In cases where the local AC source fails, the BPS-AC passes the -48 VDC from an optional battery backup to the chassis. The BPS-AC provides trickle-charging for the optional battery backup box and overcurrent protection for the Cisco 6705 chassis.

The LEDs on the BPS-AC module indicate chassis and module status. (See Table 1-1.)

Table 1-1: BPS-HP LED Indicators

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.
BTRY ACTV	Green Off	The chassis is running on the battery backup box. The chassis is running on AC power.
BTRY LOW	Yellow Off	The battery backup box is providing between -45 VDC and -42.5 VDC to the chassis. The battery backup box is providing sufficient power to the chassis, or the chassis is running on AC power.

Connectors

The BPS-HP module provides a three-prong AC connector for use with a standard AC power cord.

Caution During battery backup operation, when the battery voltage drops below -42.5 VDC, the Cisco 6705 will shut down.

Main Control Card, Integrated

The main control card, integrated (MCC-INT) module with stratum 4 clock performs centralized processing, synchronization, and switching functions for the Cisco 6705.

The MCC-INT module supports the following functions:

• TDM and ATM interfaces with the line interface modules

• Alarm processing and management

• TDM and ATM centralized switching functions

Available Slots

The MCC-INT module must be placed in the designated-purpose slot labeled MCC.
