ISDN Networking
Refer to Appendix (page 237) for an example of setting up a network using ISDN or
IP connections.
ISDN Networking is only available for the Aspire M/L/XL system. In addition, the
NTCPU must have a Feature Upgrade or Enhanced PAL chip installed.
Using Q.931-based proprietary protocol, Basic Rate Interface and Primary Rate Interfaces are
available for networking Aspire systems. PRI ISDN available with Aspire M/L/XL only. Using
ISDN Networking, the system provides up to 256 B-channel ports which can be used for Network-
ing. One PRIU or BRIU PCB is required for connection to each networked system. A minimum
version of Þrmware is required for the ISDN PCB.
BRIU PCB - Firmware 2.6
PRIU PCB - Firmware 2.0
A PRIU circuit will take 24 ports and each BRI circuit will take 2 ports. These ISDN Networking
ports are independent of the trunk and station ports available on the system.
Telco Requirements
BRI
● Peer-to-Peer
● U-Point to Telco
● NI1/NI2 (National Standard 1 and 2) Compliant
● The system provides compatibility with ISDN Basic Rate (BRI) services, including:
· Basic BRI Call Control (BCC)
· Point-to-Point BRI Terminal Connection (no daisy-chaining)
· Point-to-Multipoint BRI Terminal Connection (daisy-chaining)
· Capacity of 96 BRI circuits and 192 BRI channels
PRI
● ESF/B8ZS
● DID (routes on the last 8 digits)
● Yield to Glare Customer Side
● Outbound Caller ID Number
● Inbound Caller ID Name and Number (as provided by the telco)
● NI1/NI2 (National Standard 1 and 2) Compliant
● FAS (Facility Associated Signaling) - D-channel resides on PRI
PRI Networking With Two Local Voice Mails, Masters Must Have Different
Numbering
When programming a PRI network with each system having their own local voice mail, the master
numbers for the voice mails must be deÞned in different series in Program 11-01. The second digit
of the extension number can not be the same. For example, 700 and 701 will not work, however 700
and 710 can be used.
Ring Groups
Ring groups are NOT shared between networked systems. The only way you can ring a phone in
Site A and Site B at the same time is to DIL a trunk to an extension or a virtual extension at Site B
and program Call Forward Both Ring to an extension or virtual extension at Site A.
