AspireNet - ISDN PRI

5.2 AspireNet - ISDN PRI
AspireNet Primary Rate ISDN is supported on the standard PRTA Blade's. Each PRTA Blade can be set
independently to Trunk / S0 / AspireNet mode.
When set to AspireNet a PRTA Blade will require 30 of the AspireNet ports on the system, there are a total
of 256 AspireNet ports available.
The example below shows two SV9100 systems, each has a PRTA Blade installed which are set to Mode
4 for AspireNet . The two PRTA Blade's are cross connected via a 2-pair twisted cable.
SV9100 A has extension numbers in the range 200-299, SV9100 B has 300-399.
More than one circuit required.
If more PRI PCBs were added then Program 10-03-xx would copied for each new PCB.
CRC-4 Setting
The choice of CRC-4 on/off is not important in the example. When connected to external PRI equipment
ensure that this option is set the same as the external equipment.
Master/Slave setting
The choice of Master/Slave of each circuit is not important in the example above as there is no ISDN Net-
work connection to either of the systems.
If System A had an ISDN Network connection (BRI trunk or PRI trunk) then System A would be the Master
for AspireNet circuits.
If both system A and System B have an ISDN Network connection then the setting of Master/Slave is not
important.
When the AspireNet PRI circuit is connected to external equipment then ensure that the equipment is set
to Master (Clock generator) or Slave (Clock receiver) accordingly.
Limit the Quantity of B-Channels available
Use Program 10-32-01 to limit the quantity of channels available.
