Chapter 2: About the HSIM-W6

•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 following electrical signal interfaces (see the Synchronous WAN Configuration Window section in Chapter 4 for specific cable part numbers):

•EIA-RS449

•V.35

•EIA-RS232D

•X.21

•EIA-RS530

•EIA-530A

•RS530 ALT A

•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 or Fractional E1 using 56 or 64 Kbps timeslots with a total throughput of up to 2 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 or Fractional T1 using 56 or 64 Kbps timeslots and also provides a second Drop-and-Insert interface, which allows more than one device to share a single T1 connection.

•The WPIM-S/T provides an Integrated Services Digital Network (ISDN) 128 Kbps Basic Rate Interface (BRI) for the HSIM-W6. The WPIM-S/T provides an ISDN back-up link for a remote site or branch office when the main WPIM for a frame relay or leased line loses a connection or becomes disabled. An NT-1 adapter is necessary for this interface in the United States.

•The WPIM-HDSL provides a connection for users in a campus environment, or have access to local subscriber loops, who want to send their data over their existing telephone lines, that may run between floors, buildings, or other physical structures, at rates of up to 1.544 Mbps. HDSL supports line lengths of up to 3, 657 meters (12,000 feet) over 24 AWG (American Wire Gauge) Unshielded Twisted Pair (UTP) cabling.
