Chapter 1: Overview of the SSR-600
1-2 SSR-600 Installation Guide
• The SWPIM-DDS provides a 56 Kbps or 64 Kbps Digital Data
Service (DDS) connection. The SWPIM-DDS supports remote CSU
diagnostic or 64 Kbps clear channel loopback and non-latching remote
DSU diagnostic loopback.
• The SWPIM-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 SWPIM-E1 provides both Full E1 or Fractional E1 using 56
or 64 Kbps Time Slots with a total throughput of up to 2.048 Mbps
(1.984 Mbps payload bandwidth).
• The SWPIM-BRI provides an Integrated Services Digital Network
(ISDN) 64 or 128 Kbps Basic Rate Interface (BRI) for the SSR-600,
and supports both the S/T-interface and the U-interface. The
SWPIM-BRI can be used for Dial-up access. The SWPIM-BRI can
also provide an ISDN back-up link for a remote site or branch office
when the main SWPIM 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.
1.1.2 Ethernet LAN Connection
The SSR-600 provides 10/100 Mbps Ethernet/IEEE 802.3 support
through two fixed front panel Fast Ethernet ports.
1.1.3 FLASH EEPROMs
The SSR-600 uses a FLASH Electrically Erasable Programmable
Read-Only Memory (EEPROM) that allows new firmware to be
downloaded using BootP or TFTP protocols.
