Chapter 2: About the CSX200
• The WPIM-SY provides a synchronous serial connection of up to 2.048 Mbps to external
communications equipment (e.g., a multiplexer or CSU/DSU). The WPIM-Sync uses a
subminiature 26-pin connector that supports the electrical signal interfaces listed below.
Appendix A, WPIM Cable
assignment information for the following electrical signal interfaces: EIA-RS449, V.35,
EIA-RS232D, X.21, EIA-RS530, EIA-530A, RS530 ALT A, and RS530A ALT A
• The WPIM-DDS provides a 56 Kbps or 64 Kbps Digital Data Service (DDS) connection. The
WPIM-DDS supports remote CSU diagnostic, or 64 Kbps clear channel loopback and
non-latching remote DSU diagnostic loopback.
• The WPIM-E1 provides an E1 interface through a front panel RJ45 port and includes a built-in
CSU/DSU for direct connection to an E1 line. The WPIM-E1 provides both Full E1(32 time
slots) or Fractional E1 (less than 32 time slots) using 56Kbps, or 64 Kbps per time slot with a
total throughput of up to 2.048 Mbps.
• The WPIM-DI provides a T1 interface through a front panel RJ45 port and includes a built-in
CSU/DSU for direct connection to a T1 line. The WPIM-DI provides both Full T1 (24 time
slots) or Fractional T1 (less than 24 time slots) using 56Kbps-, or 64 Kbps per time slot. The
WPIM-D1 also provides a second Drop-and-Insert interface, which allows more than one
device, such as a PBX, to share a single T1 connection.
• The WPIM-S/T provides an Integrated Services Digital Network (ISDN) 128 Kbps Basic Rate
Interface for the CSX200. An NT-1 adapter is necessary for this interface in the United States.
• The WPIM-HDSL provides a 1.544 Mbps connection for: users in a campus environment, or
for access to local subscriber loops. The WPIM-HDSL uses existing telephone lines between
floors, buildings, or other physical structures. HDSL supports line lengths of up to 3, 657 meters
(12,000 feet) over 24 AWG Unshielded Twisted Pair cabling.

Ethernet LAN Connection

The CSX200 provides 10 Mbps Ethernet/IEEE 802.3 support through twelve (11 if Call Backup is
enabled) 8-pin RJ45 10BASE-T ports on the front of the unit (see
Repeater Functionality —
10BASE-T specifications, and provides the flexibility to connect networks using IEEE 802.3,
Ethernet Version 1 or Version 2 equipment. The CSX200 transmits retimed data packets,
regenerates the preamble, extends fragments, and arbitrates collisions. The CSX200 automatically
partitions problem segments, and reconnects repaired segments to the network. This feature
minimizes the impact on network operation resulting from a problem on one segment by isolating
the problem segment. Only devices on the problem segment are affected. When the problem is
solved, the CSX200 automatically reconnects the isolated segment to the network.
