PRODUCT COMPATIBILITY
The following sections describe the compatibility among versions of Campus
products.
Compatibility with Earlier Campus Products
When mated with a Campus-RS desktop unit or Campus-RS line unit, the
Campus-REX2 RS 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 earlier Campus Products, the
following configuration options must be set on the Campus-REX2:
• 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 “Selecting HDSL Parameters”
on page 21.
