Quad 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 Quad CT1/E1 GPIM does not support channelization.
The Quad CT1/E1 GPIM provides the physical connection to T1 or E1 network media types and also
performs T1 or E1 framing and line-speed signaling.
NOTE:
Only the SRX650 Services Gateway supports hot-swappable functionality for GPIMs.
The SRX550 Services Gateway does not support hot-swappable functionality for GPIMs.
Figure 32 on page 124
shows the Quad CT1/E1 GPIM.
