1. Pre-requisites
1.1 AS4000 FA Voice Shelves
There are no prerequisites for FA voice Shelves
Notes:
1) Free choice of RW codes (1-15) for testing. (RW15 recommended as reserved code
for survey work).
2) Network access to the 64kbits/s loopback for BER testing has to be arranged to
support link BER testing (see Figures 1, 2, and 3 ). Airspan recommend the use of
RW15 as the designated survey channel so that time slot access and switch port
mappings can be pre defined. For RW15 the loopback channel will be on TS31 of
the PCM stream from the Modem Shelf towards the switch.
3) Normal Sitespan test options are available to select test loops on both 64kbit/s
channels back towards the network if required. –This is done by reserving the
channel on TU, select the required loopback mode and applying the loopback.
