Dual CT1/E1 GPIM Overview


A Gigabit-Backplane Physical Interface Module (GPIM) is a network interface card (NIC) that installs in the front slots of the SRX550 or SRX650 Services Gateway to provide physical connections to a LAN or a WAN. The GPIM receives incoming packets from a network and transmits outgoing packets to a network.


The Dual CT1/E1 GPIM does not yet support channelization.

The Dual CT1/E1 GPIM provides the physical connection to T1 or E1 network media types and performs T1 or E1 framing and line-speed signaling.


Only the SRX650 Services Gateway supports hot-swappable functionality for GPIMs. The SRX550 Services Gateway does not support hot-swappable functionality for GPIMs.

The Dual CT1/E1 GPIM can be plugged into any GPIM slot on the services gateway. Figure 1 shows the Dual CT1/E1 GPIM.
