Chapter 2 - Configuring HDSL Parameters

Selecting HDSL Parameters

You can use the default HDSL setting for your Campus-RS unit (when also using the default settings on the remote unit to which this unit connects) which are:

•standard for the HDSL operating mode

•auto for the transceiver mode (determines which device is the master or slave)

•T1 for the HDSL rate

If you want to change any of these parameters, select one of the following sections based on the HDSL operating mode you will use. Campus-RS offers these two HDSL operating modes:

•Standard mode (page 22) provides compatibility between a Campus-RS product and an earlier Campus product (legacy Campus) that has a HDSL interface including T1, E1, or 768:

–for T1, the maximum transmission rate is 1.544 Mbps over 2 pairs

–for E1, the maximum transmission rate is 2.048 Mbps over 2 pairs

–for 768, the transmission rate is 768 kbps over 1 pair

•Extended mode (page 23) provides a fractional rate selection between the HDSL interfaces of two Campus-RS products. The rate is selectable as follows:

–for 1 pair in 64 kbps increments, starting at 128 kbps up to 2.304 Mbps

–for 2 pair in 128 kbps increments, starting at 256 kbps up to 4.608 Mbps
