Port Numbering Conventions

Port Numbering Conventions

Port numbering conventions for the Cisco VG350 Voice Gateway are as follows:

Two Compact Flash slots, CF0 and CF1.

GE ports are 10/100/1000 BASE-T, numbered GE 0/0 through GE 0/2.

10/100BASE-T ports are numbered 10/100BASE-T 0/0 and 10/100BASE-T 0/1 from right to left.

FXS voice port numbering begins at 2/0/0 to 2/0/71 or 2/0/47 and 4/0/0 to 4/0/71 or 4/0/47, depending on the number of voice ports.

The ports numbered 2/0/x are for the SM installed in slot 1 and the ports numbered 4/0/x are for the Service Module (SM) installed in slot 2.

Connecting to the Double-Wide High Density Service Module Ports

Three RJ-21 female connectors are available on the SM-D-72FXS service module. The middle RJ-21 connector accesses FXS ports 0 to 23, the left RJ-21 female connector accesses ports 24 to 4, and the right RJ-21 connector accesses ports 48 to 71. Use RJ-21 male connector to connect from the DWSM RJ-21 ports to an FXS port RJ-11 distribution box.

Note Use an RJ-21 cable with Amphenol 50-pin connectors.

Online Insertion and Removal

The DWSM can be hot-inserted into the VG350 Voice Gateway without any potential of electrical damage either to the SM or the Host because the Online Insertion and Removal (OIR) logic is present on all SM designs.

OIRl is the ability to insert and remove an SM while the system is running without causing electrical damage to the SM or Host and without interfering with the operation of any other modules or portions of a running system.

The basic feature for OIR support on an SM is the control and isolation of the 12V power rail via a field-effect transistor (FET). This FET is enabled in a controlled fashion after the SM card is fully inserted.
