Ocu Dp Access Module (P/N 1180005L1); U-Br1Te Access Module (P/N 1180020L1); E&M/To Access Module (P/N 1180402L1); Dual V.35 Access Module (P/N 1180025L1) - ADTRAN Total Access 850 System Manual

Total Access 850 System Manual Section 1 System Description

OCU DP Access Module (P/N 1180005L1)

This module is only available in Total Access 850 systems using a BCU. The OCU DP module is a single
port access module used to provide the interface between a DS0 time slot on the T1 and a 4-wire DDS
device at the customer premises. The OCU DP supports up to 18 kft of copper for remote DSU
connectivity.

U-BR1TE Access Module (P/N 1180020L1)

The UBR1TE is a module that plugs into a single access slot of the Total Access 850. It provides an ISDN
U-interface and allows transport of Basic Rate 2B+D information over T1 carriers and twisted pair wiring.
E&M/TO Access Module (P/N 1180402L1)
This module is only available in Total Access 850 systems using a BCU. The E&M/TO module is a single
port Ear and Mouth/Transmit Only access module. The primary application for this module is to provide
PBX foreign exchange at the customer premises or tandem central office applications. This module is
intended for interface with intra-building wiring. The E&M/TO module supports both 2- and 4- wire
operation.

Dual V.35 Access Module (P/N 1180025L1)

The Dual V.35 Access Module is a DSU data port with two circuits that each deliver serial data over a V.35
interface. The module is designed as a dual slot module; it requires two slots in the Total Access 850
chassis. Each circuit of the Dual V.35 Access Module provides up to 24 channels of data in 56 or 64 kbps
increments. Design operation is to transmit or receive high rate synchronous data from data terminal
equipment (DTE) over a T1 interface. This module is currently only supported by the TDM version of the
T1 RCU.
DSX-1 Access Module (P/N 1200385L1)
This module is only available in Total Access 850 systems using a T1 RCU. The DSX-1 Module installs
into the Total Access 850 system to provide an additional DSX-1 interface (RJ-45) for support of multiple
PBXs or other equipment with a DSX-1/FT1 interface. The module is functional in any of the six Total
Access 850 module slots.

Single DS0 DP Access Module (P/N 1180003L1)

This module is only available in Total Access 850 systems using a BCU. The DS0 Dataport is a single port
access module that serves as an interface to the basic DDS DS0 (64 kbps) signal to a T-carrier line.This
module is used in conjunction with an ADTRAN All-Rate Office Channel Unit (OCU) dataport or Total
Reach DDS dataport located at the end office to extend the DDS network to an end office which has
exclusively-served voice channels.
