Product Overview
Dual-port T/E1 Physical Interface
Module (PIM) are for use with the
Juniper Networks J2320, J2350, J4350,
and J6350 Services Routers, as well
as the Juniper Networks SSG140,
Product Description
The Juniper Networks Dual-port T1/E1 PIM provides the physical connection to T1 or E1
network media types, receiving incoming packets from the network and transmitting
outgoing packets to the network. The Dual-port T1/E1 PIM is equipped with a dedicated
network processor that forwards incoming data packets to the Routing Engine, and
receives outgoing data packets from the Routing Engine. During this process, the PIM
performs T1 or E1 framing and line-speed signaling.
SSG320M, SSG350M, SSG520M and
When a Dual-port T1/E1 PIM is installed in a Juniper Networks® SSG Series Secure Services
SSG550M Secure Services Gateways.
Gateway running ScreenOS® Software, the dedicated network processor will forward
traffic to the SSG Series CPU where traffic decisions are made based upon security
Features and Benefits
Dual-port T1/E1 PIM provides the following benefits:
• Dual-port form factor allows for increased bandwidth capabilities while making
effective use of the J Series and SSG Series modular interface slots.
• Integrated channel service unit/data service unit (CSU/DSU) eliminates the need to
deploy a separate external device, saving valuable space and simplifying management.
• Fully integrated CSU/DSU
• Full and fractional T1/E1 capabilities
• Onboard network processor
• 56K and 64K modes support
• ANSI T1.102, T1.107, T1.403 T1 support
