Chapter 2: About the CSX2002-2CSX200 Installation Guide• The WPIM-SY provides a synchronous serial connection of up to 2.048 Mbps to externalcommunications equipment (e.g., a multiplexer or CSU/DSU). The WPIM-Sync uses asubminiature 26-pin connector that supports the electrical signal interfaces listed below.Appendix A, WPIM Cable Specifications, provides complete part number and cable pinassignment 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. TheWPIM-DDS supports remote CSU diagnostic, or 64 Kbps clear channel loopback andnon-latching remote DSU diagnostic loopback.• The WPIM-E1 provides an E1 interface through a front panel RJ45 port and includes a built-inCSU/DSU for direct connection to an E1 line. The WPIM-E1 provides both Full E1(32 timeslots) or Fractional E1 (less than 32 time slots) using 56Kbps, or 64 Kbps per time slot with atotal throughput of up to 2.048 Mbps.• The WPIM-DI provides a T1 interface through a front panel RJ45 port and includes a built-inCSU/DSU for direct connection to a T1 line. The WPIM-DI provides both Full T1 (24 timeslots) or Fractional T1 (less than 24 time slots) using 56Kbps-, or 64 Kbps per time slot. TheWPIM-D1 also provides a second Drop-and-Insert interface, which allows more than onedevice, such as a PBX, to share a single T1 connection.• The WPIM-S/T provides an Integrated Services Digital Network (ISDN) 128 Kbps Basic RateInterface 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, orfor access to local subscriber loops. The WPIM-HDSL uses existing telephone lines betweenfloors, 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 ConnectionThe CSX200 provides 10 Mbps Ethernet/IEEE 802.3 support through twelve (11 if Call Backup isenabled) 8-pin RJ45 10BASE-T ports on the front of the unit (see Figure 2-1).Repeater Functionality — The CSX200 fully conforms to the IEEE 802.3 Repeater, AUI, and10BASE-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 automaticallypartitions problem segments, and reconnects repaired segments to the network. This featureminimizes the impact on network operation resulting from a problem on one segment by isolatingthe problem segment. Only devices on the problem segment are affected. When the problem issolved, the CSX200 automatically reconnects the isolated segment to the network.
