This section describes the network and user termination configuration set-
tings for the Octal BRI S/T Module when using the
D
IAL
P

menus. The
following configurations are provided here:
• Octal BRI S/T Module: User Termination on page A-36
OCTAL BRI S/T MODULE INTERFACE JUMPER SETTINGS
The Octal BRI S/T Module interfaces provide the capability to individually
configure both the terminal resistance and line power using two sets of
jumpers located on the module board behind the port interfaces.

ESISTANCE
(T

)
By default the terminal resistance for each port of the Octal BRI S/T Module
is set at 100
Ω
. For this configuration, both jumpers labeled T
ERM
R
ES
must
be in the O
N
position (the O
FF
pin left uncovered).

OCTAL BRI S/T MODULE: USER TERMINATION
The Octal BRI S/T Module acts like the network while interfacing to user
equipment (terminal adapters). When you are working in the network ter-
mination section of the
D
IAL
P
LAN
menu and S
LT
is defined as a S/T BRI
module, the following interface configuration options are available:
ADTRAN does not recommend changing the Terminal Resistance
jumpers to the
O
FF
position.
