PA-2T3+产品简介

To support the widest range of operational PA-2T3+思科原装线卡模块environments and to offer the greatest flexibility in provisioning clear- channel DS3 connections, the PA-T3+ and PA-2T3+ port adapters take a groundbreaking step and bring together proprietary subrate and scrambling features PA-2T3+思科原装线卡模块of T3 DSU vendors Digital Link, Larscom, and ADC Kentrox. Subrate support in the PA-T3+ and PA-2T3+ port adapters maximizes the application of these products in service provider environments for tiered DS3 services. By simultaneously supporting interoperability with a wide range of third-party PA-2T3+思科原装线卡模块DSU vendors, the PA-T3+ and PA-2T3+ port adapters offer the flexibility to support installed equipment without locking customers into a proprietary solution.

The PA-T3+ PA-2T3+思科原装线卡模块and PA-2T3+ one- and-two port T3 port adapters provide direct connectivity to T3 lines for full- duplex communications at the DS3 rate of 44.736 MHz. Each T3 port consists of a pair of 75-oPA-2T3+思科原装线卡模块hm BNC coaxial connectors, one for transmit data and one for receive data, along with six LED indicators for line status. Using the PA-2T3+ port adapter on the Cisco 7500 Series router, up to four T3 ports can be operated simultan- eously on each Versatile Interface Processor (VIP2-40 and higher). On the Cisco 7200 Series router, up to six T3 ports can be supported. On the 7400 Series router, up to 2 can be supported.PA-2T3+思科原装线卡模块
