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.
NOTE: 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.
NOTE: Only SRX650 Services Gateway supports hot-swappable functionality
for GPIMs.
The Dual CT1/E1 GPIM can be plugged into any GPIM slot on the services gateway. Figure
39 on page 150 shows the Dual CT1/E1 GPIM.
