Juniper SRX-GP-DUAL-T1-E1 Gigabit Ethernet network switch module

2-Port CT1/E1 GPIM, 1Gbps 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. These modules will complement the onboard Ethernet interfaces to extend the types and port counts of network connections for the LAN or WAN.
