Chapter 3 Configuring the Cisco IPVC 3500 Series Gateway
Configuring Gateway Settings
Note
In European networks, Layer 1 is usually only activated during a call. In such a system, Layer 1
line hunting is not effective and should not be enabled. However, when the gateway BRI port is
connected to a private branch exchange (PBX,) for some PBX, Layer 1 always activates.
Step 17
Select the Enable static TEI check box to configure a static TEI. TEI values are supplied by the telecom
company. If you select this option, perform step 17. Otherwise, skip to step 18.
Note
You can only configure this setting if you select 5ESS PTP or ETSI PTP in the Signaling
Protocol field of the Physical Interface section.
Step 18
In the TEI Value (0-63) field, enter a value from 0 to 63 for this BRI line.
Step 19
Click OK to upload your changes to the gateway database and close the Advanced dialog box.
Configuring PRI Port Physical Interface Settings
Note
This section applies only to the Cisco IPVC 3500 PRI Gateways.
In the Physical Interface section of the PRI Port tabs, you can configure the physical line properties of
the specified PRI port.
Procedure
Step 1

In the Interface field, choose the line interface: T1 or E1 .
Step 6
In the Country field, choose the nation where the ISDN service is installed.
Step 7
In the Signaling protocol field, choose the signaling protocol used to setup and tear down the calls
through the signaling (D) channel. Depending on the interface used, different signaling protocols are
available.
Step 8 In the Network access field, choose the gateway national access type: TE (Terminal Equipment) or NT
(Network Terminator) device.
Step 9
In the Clock source field, choose the gateway clock source:
•
Master (the gateway provides the clock signal)
•
Slave (the gateway receives the clock signal)
Step 10
In the Line Build Out field, choose Long Haul or Short Haul .
