Campus-RS Fractional Interface Card Compatibility
When mated with a Campus-RS Desktop Unit or Campus-RS Line Unit (see
“Campus-RS Desktop and Line Unit Compatibility”), the Campus-RS
Fractional Interface Card is compatible, over the HDSL link, with earlier
versions of Campus products, such as the Campus-T1, Campus-E1, and
Campus-768, as shown in the following illustration.
All earlier versions of Campus products are manufactured to operate at a
single HDSL transmission rate, while the Campus-RS transmission rate is
user-selectable. To support compatibility with the application shown above,
the following configuration options must be set on the Campus-RS Fractional
Interface Card:
• Set the HDSL Operating Mode to Standard Mode
• Set the Standard Mode HDSL Rate to T1, E1, or 768, to match the rate
of the earlier product.
For information on setting these options, see “Set the HDSL Operating
Mode” on page 3-2.
