Сетевой модуль для маршрутизатора Cisco Systems PA-4T 4-Port Serial Network Module (adapter)

Описание

Each port also supports a variety of interface types, determined by the separately purchased cable type connected to it. Supported interfaces include EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530, allowing flexible deployments as either DCE or DTE equipment. The four-port adapter is the most cost-effective solution for low-traffic WAN connections or remote Cisco 7200 installations.

The PA-4T+ is supported on the Cisco 7200, C7301, C7304, C7500 and C7600. The PA-4T+ port adapter requires only a single slot in a Cisco 7200 Series and 7301 routers. For the Cisco 7304, it requires the port adapter carrier card option. For Cisco 7500 Series routers, it requires one of the two available adapter slots on a Versatile Interface Processor (VIP2) and an Enhanced FlexWan on the Cisco 7600.

Преимущества 

•Cost-effective solutions for any environment

•Delivers very low price-per-port and provides higher performance than comparable solutions

•Provides low-cost entry for small enterprise WANs

•Provides Internet Service Providers (ISPs) with high serial density for Cisco 7200 series routers, lowering cost per port and cost per subscriber

•Four-port design provides flexibility

•Supports four full-duplex T1/E1 connections or a single full-duplex E2 connection

•All ports use identical 60-pin, D-shell receptacle that supports all interface types (i.e. RS232, RS449, RS530, V.35, x.21)

•Adapter cables determine the electrical interface and port mode data terminal equipment (DTE) or data communications equipment (DCE)

•Carrier-Class Reliability and Serviceability

•Field-replaceable design permits online insertion and removal for continuous router availability

•Port adapter handles simplify installation and removal

•Support for loopback for remote diagnostics

•LEDs indicate when the adapter is enabled for operation

•Separate LEDs for each port indicate DTE or DCE function, transmit data, transmit clock, receive data, and receive clock signals

•Metric (M3) thumbscrews included with each port adapter cable allow connections to devices that use metric hardware
