Cisco Small Form-Factor Pluggable Ethernet-to-T3 Remote Bridge
Available Languages
Product Overview
The Cisco® Small Form-Factor Pluggable (SFP) Ethernet-to-T3 Remote Bridge forwards Gigabit Ethernet packets to a WAN based on time-division multiplexing (TDM) at full-duplex T3 wire speed, fully using the expensive T3 TDM bandwidth to take advantage of existing DS3 linkage to provide an end-to-end Radio Access Network (RAN) backhaul solution.
SFP remote bridge applications include the following (Figure 1):
● Transparent LAN services over leased lines
● Remote branch-office connectivity over T3 lines
● Connection of LANs over T3 radio links or in campus applications
Features and Benefits
● Supports standard generic framing procedure (GFP), High-Level Data Link Control (HDLC), and Cisco HDLC (cHDLC) encapsulation protocols
● Provides T3 connectivity to Ethernet
● Provides full-duplex, T3 wire-speed packet forwarding
● Supports 64- to 10,000-byte frame sizes for Gigabit Ethernet, including VLAN-tagged frames
● Transparently directs LAN traffic
