5.2.1 Unlocking the Abis Interface
The Abis interface between the BSC and BTS is established via a PPP link over E1
or T1 lines. Make the E1 or T1 connections to the provider and set up the Abis
signaling link to the OMC as described in Chapter 4 - Off-Line Commissioning of a
Daisy Chain. Once the Abis link is established it must be unlocked at the OMC to
allow the BSC to download the TRX code to the BTS. Refer to the UltraVIEW OMC
Configuration Guide for procedures to unlock the Abis. As the code downloads,
the TRXs run POST to verify their operation. This takes up to fifteen minutes
depending the number of TRXs in the system.
Figure 5-2 illustrates the LED display during the POST process and Figure 5-3
illustrates the final LED display.
For systems equipped with multiple TRXs, the TRXs download
their code and run POST simultaneously. If viewing the output in
a serial window, the POST messages will be mixed among
different TRXs while in progress.
