PA-2T3 vs PA-MC-2T3


Another question about port adapters.

The Mulitchannel, according to Cisco:

“Multichannel” refers to the ability to support individual DS0 (64 kbps) channels, as well as T1/E1 circuits or combinations of both."

What would be the reason to need the mutlichannel adapter as opposed to needing the no channelized?

Would it be for a fractional DS3 for example?

What would be an application where seperating the channels is needed?


Re: PA-2T3 vs PA-MC-2T3

The two-port enhanced multichannel T3 port adapter platforms is the next step in port density and flexibility for enterprise and Internet service provider WAN link aggregation. Each adapter has two T3 ports that can be independently configured for either multichannel T3 or packet-over-T3 operation. When configured as T3 ports, connections to DS3 and subrate DS3 services can be provisioned. When configured as multichannel T3 ports, up to 56 T1 links can be brought in on this single-wide port adapter. Each T1 can be further channelized to DS0 making the two-port enhanced multichannel T3 port adapter the most flexible interface for WAN provisioning.

As a application wise two-port multichannel T3 adapter meets a variety of service interconnect requirements including concurrent support for leased line and Frame Relay. Enterprises and service providers can connect the adapters' two DS3 ports into these services for aggregation of large numbers of remote site and internet service provider (ISP) customers into a central site.
