1. GENERAL
This ractice is an installation and maintenance guide
for the ADTRAN Total Access Quad BNC Ada ter
Module illustrated in Figure 1. The 1181007L2 Quad
BNC Ada ter Module is designed to mount on the
rear of the ADTRAN Total Access chassis,
P/N 1181001L1 (23-inch) or 1182003L1 (19-inch).
The Quad BNC Ada ter Module rovides Dual STS-1
interfaces for the Total Access 3000 and Total Access
3010 Chassis. The Quad BNC Ada ter Module must
be used in conjunction with an OC-3 L2 MUX (P/N
1181031L2). It will also work in conjunction with
either the L1 or L2 versions of the STS-1 MUX (P/N
1181030L1/L2). For information on the OC-3 L2
MUX, refer to ADTRAN Document 61181031L2-5A.
Revision History
This is the initial issue of this ractice. Future
revisions to this document will be ex lained in this
subsection.
2. FEATURES
The Quad BNC Ada ter Module is designed to mount
on the lower right-hand corner of the back lane of a
Total Access 3000 or Total Access 3010 chassis. The

Access chassis which subtend from a Total Access
equi ed with an OC-3 L2 MUX.
The Quad BNC Ada ter Module for the Total Access
chassis rovides a data ath for two STS-1s from the
OC-3 equi ment Total Access to the subtending Total
Access chassis.
The Quad BNC Ada ter Module rovides:
1. Pro er receive termination for an EC-1 signal.
2. A means of interfacing the transmit EC-1 line
from either multi lexer module.
3. Four 75-ohm BNC connectors – two for
transmit data and two for receive data.
4. Connection to the Total Access back lane at
the 24- in connector rovided for that ur ose
and attaches with screws to ensure rigidity.
