Multi Protocol Test Set 225
14 PRI-ISDN Test
With the optional ISDN PRI capabilities, technicians can test from the
customer’s premises and emulate their equipment. With any butt set or
analog phone, users can talk and listen over the ISDN network. In an effort
to make testing smooth and efficient, the AXS-200/855 PRI option also
allows the ability to place/receive calls and hold 23 or 30 active channels so
a technician can then selectively choose to talk, listen or run a BER test
over any channel. Having Q.931 codes allows technicians to further
troubleshoot the call setup and make sure that the call setup, maintenance
and tear-down are properly carried out.
Note: The PRI-ISDN interface uses the T1-B/E1-B port. Refer to PRI - DUAL DS1/E1
Port on page 19 for cable connection.
