Bantam Jack Description
The front panel of the FT1 DP has DS0 splitting
bantam jacks. The metallic splitting jacks provide an
intrusive, signal-interrupting access to the first DS0
channel. It is very important to know the direction of
the access provided by a metallic splitting jack. A
description of these jacks is provided below.
Figure 2
shows the bantam jack arrangement and
details for specific jacks.

FT1 DP Bantam Jacks
A set of dual bantam jacks are on the front panel of
the Total Access 1500 FT1 DP. The jacks allow for
connection of a Tele-Path Instruments 108/109 RT II
(or equivalent) test set through one DS0 channel at 64
kbps for functions such as sending and receiving BER
signals.
NOTE
The DS0 access jacks are a logic level interface.
FT1 DP Loopbacks
Two loopbacks are available to the Total Access 1500
FT1 DP. The Total Access 1500 FT1 DP network
loopback loops the FT1 signal back to the network.
The FT1 DP CPE loopback loops the FT1 signal back
to the customer (see
Loopback Options Screen
).
These loopback capabilities are described in detail in
Appendix A
of this practice.
