Off-Line Commissioning of a Daisy Chain
Up to four WAVEXpresses can be incorporated into a daisy chain. If this configuration is adopted, each WAVEXpress/
BTS must be installed separately, and if needed, off-line commissioning procedures performed on each unit
independently. Once each unit is installed and commissioned, the WAVEXpresses can be daisy chained together.
5-1 Setting the Abis Timeslot
This procedure sets the Abis timeslot for the WAVEXpress/BTS. If the Abis timeslot is not set, it automatically defaults
to 16.
This procedure is optional for a star configured WAVEXpress/BTS but is required for all WAVEXpresses which will be
connected in a daisy chain. In this case, each WAVEXpress/BTS must have its Abis timeslot set to a unique number in
the chain. This information will be used by the OMC operator to configure the daisy chain.
Step 1
Ensure that the Craft PC is connected to the BTS over a serial line, and that a serial connection is estab-
lished. Refer to Chapter 4 for instructions on how to do this.
Step 2
In an XTerm window, type:
bts
:A->
getFlashE1Chan
This displays the timeslot reserved for the Abis timeslot, which is by default set to 16. To change this
value, type at the prompt:
bts
:A->
setFlashE1Chan
<number>
where <number> is a number between 1 and 31 and is the reserved Abis signaling timeslot for the
WAVEXpress to be daisy chained.
Step 3
To double-check that the timeslot was changed, type again:
bts
:A->
getFlashE1Chan
The new Abis timeslot number should be displayed.
NOTE
☛
WAVEXpresses and MicroXpresses can be included in the same daisy chain.
This procedure must be performed after the WAVEXpress’ are tested using a Racal
testset. Refer to the BSS Field Maintenance Guide
for further instructions.
