Separate PRI Configuration
After installation, your system should be connected similar to the figure below:
Figure 4-23: Separate PRI for Local Dialing
Installation
•
Connect a straight-through PRI cable from the network to the port labeled
Port1
on the MCK T1/PRI
card on the PBXgateway II.
•
Connect a crossover PRI cable from the PBX trunk card to the port labeled
Port2
on the MCK T1/PRI
card on the PBXgateway II. This is the Digital Trunk Line connnection between the PBX and the PBX-
gateway II.
•
Connect a network interface cable between the Central Office and the port labeled
Port2
on the MCK
T1/PRI card on the EXTender 7000.
•
Connect a straight-through PRI cable from the network to the port labeled
Port1
on the MCK T1/PRI
card on the EXTender 7000.
On the EXTender 7000, the left T1/PRI port (
Port1
) serves as the MCK EXTender link to the PBXgateway II
over the network. The right T1/PRI port (
Port2
) connects the Local CO and provides Local Dialing. In a
shared PRI configuration, you can use a single T1/PRI connection to both provide the link to the PBXgate-
way II and provide Local Dialing via the Local CO. A shared configuration is very economical because only
one T1/PRI line is required at the remote Branch Office.
Prerequisites for Configuration
•
The PBXgateway II (at the corporate site) and the EXTender (at the branch office) must be installed
properly and the network link between both devices must be operational.
•
The Management Interface (MI) parameters for the PBXgateway II must be set to match the corre-
sponding parameters on the EXTender 7000. See the
PBXgateway II System Administrator’s Guide
for
detailed instructions.
•
If the application will support PBX hosted local dialing, the T1/PRI card in the PBX must be configured
to allow users to access the digital trunk lines. See the
PBXgateway II System Administrator’s Guide
and your PBX documentation for instructions.
