Cisco 7140-8T
The Cisco 7140-8T provides eight high-speed, synchronous serial ports that support full-duplex
operation at T1 (1.544-Mbps) and E1 (2.048-Mbps) speeds. The Cisco 7140-8T provides the following
features:
• EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530 interface types
• External (data terminal equipment [DTE] mode) or internal (data communications equipment [DCE]
mode) timing signals (except for EIA-530, which only supports external)
• Loopbacks (except for X.21 DTE)
• ATM-DXI, Frame Relay, High-Level Data Link Control (HDLC), Point-to-Point Protocol (PPP),
and Switched Multimegabit Data Service (SMDS) encapsulation
• RFC 1406 (except for the Frac table)
Figure 1-23 shows the back of the Cisco 7140-8T. Access to the interfaces is located at the back of the
router.
