The PA-2T3/E3-EC module delivers great performance. It provides high-speed T3/E3 connectivity, making it an essential addition to our network infrastructure.
We rely on the PA-2T3/E3-EC for its stability and performance. It provides seamless T3/E3 connections and ensures smooth network operations.
The PA-2T3/E3-EC is a performance adapter module for Cisco 7200 Series routers that provides two fully integrated clear-channel T3/E3 ports with built-in CSU/DSU and enhanced throughput.
The PA-2T3/E3-EC module is supported in Cisco 7200 Series routers with SPC-1, SPC-2, or SPA-interface slots, including the 7206, 7206VXR, 7210, and 7248 models.
Each T3/E3 port delivers up to 45 Mbps of full-duplex clear-channel bandwidth, supporting aggregate throughput of 90 Mbps per module under optimal conditions.
It supports HDLC, PPP, Frame Relay, MPLS, channelized voice transport, Multilink PPP, and Quality of Service (QoS) features such as class-based queuing and weighted fair queuing.
The module uses two RJ-48C connectors for T3 (DS3) services and two 75-ohm BNC connectors with optional adapter for E3 services, with internal switching to select the active interface.
Yes, it incorporates integrated CSU/DSU capabilities for both T3 and E3 clear-channel links, eliminating the need for external line termination devices.
Power down the router, insert the PA-2T3/E3-EC into an available SPA or PVDM slot, secure the module with screws, power up, and verify installation via the 'show controllers' CLI command.
You need a Cisco IOS image with Advanced IP Services or Enterprise Services feature set that includes support for Multiprotocol and CSU/DSU management on PA-2T3/E3-EC.
The module uses Cisco IOS feature licensing. Ensure you have an active Right-to-Use (RTU) license for clear-channel T3/E3 interfaces in your IOS feature set.
In global config mode, enter 'interface serial 0/0', set 'clock rate 4473600', choose encapsulation (e.g., 'encapsulation hdlc'), and apply service-provider parameters with 't3 framing c_bit'.
Operating temperature range is 0°C to 40°C; relative humidity 10%–85% non-condensing; altitude up to 10,000 ft (3,048 m) without performance degradation.
