Dual V.35 Access Module (P/N 1180025L1)
The Dual V.35 module provides additional V.35 interfaces for customer premises equipment. The module
takes up two access slots; therefore three modules (six additional ports) can be added to an empty chassis.
The Total Access 850 can support a maximum of seven V.35 interfaces. V.35 ports provided by the Dual
V.35 module are accessed on the front of the Total Access 850. This module is currently only supported by
the TDM version of the T1 RCU. An ADTRAN 35 ft DB-26/V.35 adapter cable is required (P/N
1200167L1).
Faceplate LEDs
The faceplate LEDs provide status information using a color coded message format. Table 33 gives a
description of all faceplate LEDs for the Dual V.35 Module when used with the Total Access 850 system.
Interface Pinouts
Table 34 provides the interface pinout for the DB-26 and V.35 interfaces.
Table 33. Dual V.35 Module Faceplate LEDs
For these LEDs...
This color light...
Indicates that...
Status
GREEN
the module is operating normally.
RED
there is a card failure, or the T1 is down, or there is no
valid data transfer occurring.
AMBER
there is a test in progress.
Blinking AMBER
no DS0s have been assigned to the interface.
TD
GREEN
the module is transmitting data to the network interface.
RD
GREEN
the module is receiving data from the network and
transmitting it out the V.35 interface (to the DTE
equipment).
