The Cisco PA-E3 is a 1-port E3 Serial Port Adapter with integrated DSU/CSU designed for the Cisco 7200 Series routers to provide reliable 34.368 Mbps WAN connectivity.
The PA-E3 module is supported in Cisco 7200 VXR and 7200 VXR-Engines that have a Packet-Switching Engine (PSE) slot and IOS releases 12.2(25)SB or later.
The PA-E3 supports E3 (34.368 Mbps) unframed serial data and common protocols including HDLC, PPP, Frame Relay, and Cisco encapsulation over an integrated DSU.
Power down the router, insert the PA-E3 into an available PSE slot until it latches, reconnect power, and verify module presence with the show diag command.
The PA-E3 is compatible with Cisco IOS 12.2(25)SB and later feature sets supporting Enterprise/IP Base, Advanced IP Services, and Advanced Enterprise Services.
Use a male-to-male V.35 or G.703 coaxial cable with appropriate shielding and surge protection to connect the PA-E3’s RJ-48C DSU port to the service provider’s network interface.
Enter interface Serial0/x, set encapsulation (for example “encapsulation hdlc”), and assign IP using “ip address A.B.C.D E.F.G.H” followed by “no shutdown.”
The built-in DSU/CSU supports up to 4 km of E3 local loop over G.703 coaxial cable, subject to carrier specifications and line quality.
The PA-E3 features an integrated DSU/CSU, eliminating the need for an external data service unit when connecting to E3 circuits.
Use show interfaces Serial0/x to view link status, input/output statistics, and CRC error counts; for in-depth diagnostics run show controller Serial0/x.
The PA-E3 consumes approximately 15 W, operates between 0°C to 40°C, and requires 10%–90% non-condensing humidity per Cisco environmental specifications.
No, the PA-E3 is not hot-swappable; you must power down the router before removing or installing the module to avoid hardware damage.
Cisco offers a one-year limited hardware warranty on the PA-E3, with optional SMARTnet service for 24×7 support, software updates, and expedited hardware replacement.
Recommended spares include E3 G.703 cables, surge suppressors, and a backup PA-E3 module; contact Cisco or your reseller for SKUs and compatibility.
Firmware updates are bundled with Cisco IOS releases; download the latest IOS image from Cisco.com and install it via TFTP or USB, then reload the router.
