CHAPTER 1
OVERVIEW OF THE SSR-600
The SSR-600 (Figure 1-1) is a device that provides Ethernet Local Area
Network (LAN) connectivity via two fixed Ethernet ports, and offers
high-speed Wide Area Network (WAN) access to remote sites via two
optional Sliding WAN Physical Interface Modules (SWPIMs).
The SSR-600 operates from a standard ac power source.

1.1 SSR-600 HARDWARE
This section details the hardware capabilities of the SSR-600.
1.1.1 WAN Connection
The WAN connections to the SSR-600 are provided by the optional
SWPIMs. The SSR-600 supports certain WAN protocols depending on
the SWPIM installed. Refer to the appropriate SWPIM manual for
detailed information on the SWPIMs chosen for installation.
• The SWPIM-T1 provides a T1 interface through a front panel RJ45
port and includes a built-in Channel Service Unit/Digital Service Unit
(CSU/DSU) for direct connection to a T1 line. The SWPIM-T1
provides both Full T1 or Fractional T1 using 56 or 64 Kbps Time Slots,
with a total throughput of up to 1.544 Mbps (1.536 payload
bandwidth).
• The SWPIM-SY provides a synchronous serial connection of up to
2.048 Mbps to external communications equipment (e.g., a
multiplexer or CSU/DSU). The SWPIM-SY uses a subminiature
36-pin connector that supports these electrical signal interfaces:
EIA-RS449, V.35, EIA-RS232D, X.21, EIA-RS530, EIA-530A.
