COMPOSITION OF A CAMPUS-RS SYSTEM
Campus-RS products accommodate a wide range of network interfaces and
access speeds in a single platform solution. A Campus-RS system comprises
these primary elements:
• Campus-RS desktop unit—The desktop unit provides a DSL (WAN)
interface that connects to a line unit (DSL interface) in a Campus-Star
chassis or back-to-back with another desktop unit DSL interface. You
can then install any of the customer interface cards listed on page 120 for
the customer-side network connection.
• Campus-Star chassis—This chassis or concentrator provides aggregation
for up to 14 DSL line connections. Each line connection is made using a
DSL line unit that connects to a DSL line unit in another Star Chassis or
to the DSL interface of a desktop unit. You can then install any one of the
customer interface cards listed below to complement each DSL line unit
in the chassis for the customer-side network connection.
You can install a Campus-RS Management Unit (CMU) into the chassis
for SNMP management of components in the chassis and for
management of elements attached to the chassis.
• Customer interface cards—For connection to the customer network for
voice, video, and data, the following interface cards are available to
install into the desktop unit or the Campus-Star chassis:
– serial data interfaces such as RS-449, RS-530, RS-530A, V.35, and
X.21 for connections to a router or other data equipment (with this
customer interface card, the maximum DSL line connection rate can
be up to 4.608 Mbps)
– flex interface with two serial data ports for RS-449, RS-530,
RS-530A, V.35, or X.21 interfaces and one DSX-1 voice interface
(with this customer interface card, the maximum DSL line
connection rate can be up to 1.544 Mbps)
– CSU/DSU interface (with this customer interface card, the
maximum DSL line connection rate can be up to 1.544 Mbps)
– G.703 (E1) interface (with this customer interface card, the
maximum DSL line connection rate can be up to 2.048 Mbps)
– 10/100Base-T bridge/router interface (with this customer interface
