Creating Line Pools
4-55
Parameter: BRI B Channel Loopback
Default: Disable
Options: Enable | Disable
Function: This parameter is for Layer 1 ISDN BRI conformance testing. It allows
external equipment to send data to the router over the B channels and loop
it right back out the S/T interface. By doing this, the external equipment
can verify the physical connection between its equipment and the router.
Instructions: Select Enable if you want to run a loopback test between the network and
the S/T interface on the router. Note that you should never enable this
parameter when the router is in normal operational mode.
MIB Object ID: 1.3.6.1.4.1.18.3.5.9.8.9.1.13
Parameter: BRI Line Type
Default: PTP
Options: PTP | MTP
Function: Indicates whether or not you have a point-to-point (PTP) or a multipoint
(MTP) configuration on the BRI line.
Instructions: Enter the value that indicates the type of line supplied by your network
provider.
If you have a point-to-point line connected to a 5ESS switch, you do not
have to configure SPIDs. (Refer to the SPID parameter on page 4-46.)
MIB Object ID: 1.3.6.1.4.1.18.3.5.9.8.9.1.33
Modifying the Logical Lines Configuration
Before you can delete or change the logical lines in a pool, first delete all circuits
associated with that pool. Refer to Chapter 5 for instructions.
You can modify the logical lines by following these steps:
1. Select Dialup➔Demand, Backup, or Bandwidth On Demand Pools from
the Configuration Manager window.
Site Manager displays the Pools window (refer to Figure 4-2).
2. Highlight the pool ID that has the ISDN lines you want to modify and
click on Edit.
