Feature Overview
The PA-MC-STM-1 is a high-speed single-port multichannel STM-1 port adapter. You can configure the PA-MC-STM-1 as a multichannel E1/E0 STM-1 port. The PA-MC-STM-1 can be configured into 63 individual E1 links. Each E1 link can carry a single channel at full or fractional rates, or be broken down into multiple DS0 or Nx64 Kbps rates. The PA-MC-STM-1 supports up to three TUG-3/AU-3 transport slots numbered 1 through 3. You can configure each TUG-3/AU-3 to carry 21 SDH TU-12s. Each SDH TU-12 is capable of carrying a channelized E1 frame, which can be unchannelized to N*64 Kbps timeslots.

Feature Overview
PA-MC-STM-1 Multiplexing Hierarchy
Figure 1 illustrates the synchronous digital hierarchy (SDH) multiplexing structure supported on the PA-MC-STM-1. The PA-MC-STM-1 multiplexing structure is a subset of that defined in ITU-T G.707. At the lowest level, containers are input into virtual containers (VC) with stuffing bits to create a uniform VC payload with a common bit-rate, ready for synchronous multiplexing. The VCs are then aligned into tributary units (TUs) where pointer processing operations are implemented. This allows the TUs to be multiplexed into TU groups (TUGs). Three TU-12s can be multiplexed into one TUG-2.

The TUGs are then multiplexed into higher-level VCs, which in turn are multiplexed into administrative units (AUs).The AUs are then multiplexed into an AU group (AUG), and the final payload from the AUG is then multiplexed into the Synchronous Transport Module (STM).
The PA-MC-STM-1 port adapter provides the following benefits:
High-density IP aggregation
Reduction in provisioning costs
Improved cable management
Easier scaling of services
Improved network availability
Restrictions
The PA-MC-STM-1 does not support the following:
VIP2
More than 256 logical channel groups per PA-MC-STM-1
Channel-associated-signaling (CAS) for voice channels
E1 Facility Data Link (FDL)
E3 and subrate E3
