Configuring Virtual Port Mapping Table
Introduction
A T1 or E1 digital port comprises multiple logical data channels. These channels,
known as virtual ports, are not associated with any physical slot number and have no
physical I/O of their own.

Before You Begin
Obtain the timeslot assignments for all the remote nodes connecting to the
PathBuilder S24x, 26x, and 27x switch from your network services provider. You
need this information to complete the virtual ports configuration.

Function
By configuring the Virtual Port Mapping Table, a timeslot channel on a specific T1
or E1 line is mapped to a virtual port. Virtual ports are numbered from 100 to 254,
whereas ports with actual physical connections are numbered from 1 to 54.

Guidelines
The Virtual Port Mapping Table must be configured in conjunction with other
records as follows.
records as follows.
• Configure the physical port record as either T1 or E1 and all virtual ports
before you configure the Virtual Port Mapping Table.
• Configure a Virtual Port Mapping Record to assign a timeslot number per
T1/E1 channel for the application.
