1-Port Clear Channel DS3/E3 GPIM
1-Port Clear Channel DS3/E3 GPIM Overview
The 1-Port Clear Channel DS3/E3 GPIM functions as a clear channel interface that can support DS3 (T3) or E3 line rates of 44.796 or 34.368 Mbps, respectively. The device does not support channelization, but it supports a subrate DS3/E3 configuration. The DS3/E3 interface is a popular high-bandwidth WAN interface for large enterprise branch locations that enables high-quality voice, video, and data applications with reduced latency. The clear channel implementation provides such features as subrate and scrambling options used by major DSU vendors. The interface also supports loopback, bit error rate test (BERT), and far-end alarm and control (FEAC) diagnostic capabilities. It supports Frame Relay, Point-to-Point Protocol (PPP), and High-Speed Data Link Control (HDLC) serial encapsulation protocols.
The 1-Port Clear Channel DS3/E3 GPIM is suitable for:
Branch office and regional sites for medium-sized to large enterprises.
Corporate headquarters for medium-sized enterprises.
The 1-Port Clear Channel DS3/E3 GPIM supports IP configurations. Using the command-line interface (CLI), you can configure the 1-Port Clear Channel DS3/E3 GPIM to operate in either DS3 or E3 mode.
The 1-Port Clear Channel DS3/E3 GPIM can be plugged into any GPIM slot on the services gateway. Figure 1 shows the front panel of the 1-Port Clear Channel DS3/E3 GPIM..
Only the SRX650 Services Gateway supports hot-swappable functionality for GPIMs. The SRX550 Services Gateway does not support hot-swappable functionality for GPIMs.
