Compare Cisco (WS-X6101-OC12-SMF-RF) Expansion Module to Cisco (PA-MC-STM-1SMI=) Expansion Module

Deployable across the Catalyst 6000 family of switches, new Asynchronous Transfer Mode (ATM) OC-12 dual-PHY uplink modules from Cisco Systems deliver high-speed Layer 2 and Layer 3 connectivity across ATM networks. Support for both ATM Forum standard LAN Emulation (LANE) and Multiprotocol over ATM (MPOA) enables the Catalyst 6000 Family of switches to connect to ATM backbones, providing scalable, intelligent switching with value-added high availability services. Service Provider and Enterprise customers alike can take advantage of support for RFC 1483 Permanent Virtual Circuits (PVC's) with traffic shaping to extend transparent LAN services across wide area ATM networks. In addition, future support for end-to-end Quality of Service (QoS) will enable enterprise voice solutions and services to seamlessly coexist between Ethernet and ATM backbones. Less

The PA-MC-STM-1 is a single-wide STM-1 port adapter designed to address the demand for SDH network connections on the Cisco 7600, 7500, 7200, and FlexWAN modules. The port adapter enables users to channel an STM-1 down to 64 Kbps using a variety of encapsulations on as many as 256 logical channels. The time slots in each E1 can be grouped into several individual logical channels, each of which can carry data with different data link layer protocols. The PA-MC-STM-1 enables service providers to use a single fiber-optic circuit to provision 63 E1s-E1s that normally require 63 separate copper pairs. The PA reduces wiring complexity, and, when spare capacity is available, it enables service providers to "turn up" new E1s without dispatching a technician to the router. For service providers with customers who require smaller circuits, the PA-MC-STM-1 supports as many as 256 channel groups and can provision circuits down to DS0-providing even more flexibility and density.
