Cisco Four-Port Channelized E1 Frame Relay Port Adapter for LS1010, Catalyst 8510, and Catalyst 8540
The Cisco four-port channelized E1 Frame Relay port adapter is designed for use with the LS1010 and Catalyst 8500 MSR editions. This 4xChannelized E1 Port Adapter Module (PAM) provides four E1 interfaces for full-duplex communications at up to 2.048 Mbps. Each E1 line supports up to 31 channels (logical ports) for a total of 124 channelized Frame Relay ports on a single, half-slot port adapter module. Each E1 line consists of an RJ48C along with LED indicators for line status.
Fractional E1 ports as well as unchannelized E1 are supported on this PAM in order to provide a high degree of bandwidth flexibility to meet the growing capacity requirements of service carriers. Standards-based adaptation technology, a high degree of configuration flexibility, and advanced quality of service (QoS) and traffic management features in a moderately dense port configuration, combine to make the 4xChannelized E1 Frame Relay PAM a very cost-effective solution.

This PAM supports both Frame Relay UNI and Frame Relay NNI service interfaces, which can be configured on a per-port basis. Frame Relay to ATM network interworking (FRF.5) and Frame Relay to ATM service interworking (FRF.8) are fully supported and can be configured on a per-permanent virtual circuit (PVC) basis.
Traffic is mapped between these Frame Relay service interfaces and the ATM backplane of the LS1010, Catalyst 8510, or Catalyst 8540 using standards-compliant adaptation. Per VC queuing and intelligent Cisco QoS management features provide flexible and cost-effective per-VC control for connection-based service-level agreements (SLAs).
The four-port channelized E1 Frame Relay PAM is supported by standards-based management tools, including Simple Network Management Protocol (SNMP), Trivial File Transfer Protocol (TFTP), and the advanced Cisco IOS® command-line interface (CLI).
