High Density Channelized Access Solution

PMC-SierraM8316 TEMUX-84 high density channelized access solution is well-suited for Metro Optical Access, Multi-service Switches and Multi-Protocol Label Switching (MPLS) Edge Router equipment. The system supports the global requirements for framing, mapping and multiplexing of T1, E1, T3, E3 channels into SONET/SDH services. By reducing board space to one quarter of that required using available competitive solutions, the system allows T1, E1, T3 and E3 access port card design densities to scale to OC-48.

The solution provides the next key element to extend the company's access services architecture by enabling next generation equipment to deliver channelized OC-48 line cards. The architecture supports a number of existing and emerging services including Frame Relay (FR), Internet Protocol (IP), Dedicated Private Line, ATM, Integrated Voice and Data, Voice-over- IP and Voice-over-ATM.

The company's complete portfolio of high density SONET/SDH line interface solutions including SPECTRA-155, SPECTRA-4x155, SPECTRA-622 and SPECTRA-2488 connect with the system. The device supports a Scaleable Bandwidth Interconnect (SBIT) bus to connect to FREEDM packet processors and AAL1gator AAL1 SAR products. It also supports an H-MVIP bus to interconnect to the MECA-4A Voice-over-ATM processor or to the MECA-4I Voice-over-IP Processor.

The device provides framing and multiplexing for 84 T1 channels or 63 E1 channels into 3 channelized DS-3's or alternatively maps the T1/E1 channels directly into a SONET/SDH aggregate. For higher line rate applications, 4 TEMUX-84's will support a channelized OC-12 data stream, 16 TEMUX-84 devices will support a channelized OC-48 data stream.
