MSF15
155 Mbps Multi-Service Framer

The MSF15 is a highly integrated Multi-Service Framer device capable of mapping both Telecom and Datacom traffic into protected OC-3/STM-1 SONET/SDH transport payloads. The MSF15 is equipped with multiple voice, leased line and data service interfaces - such as 10/100 Ethernet, Gigabit Ethernet, DS1/E1, and DS3/E3. Ethernet over SONET/SDH (EoS) is supported through Virtual Concatenation (VC) with Link Capacity Adjustment Scheme (LCAS), with simultaneous use of mixed High-Order (STS/VC paths) and Low-Order (VT/VC paths).

The MSF15 is a highly integrated device capable of mapping both Telecom and Datacom traffic into SONET/SDH transport payloads. On the line side, the MSF15 supports protected OC-3/STM-1 interfaces. On the client side, Ethernet (10/100/1000 Mbps), DS1/E1 and DS3/E3 interfaces are available.

The MSF15 maps up to 155 Mbps of traffic from a variety of client side interfaces. Traffic destined for the SONET/SDH trunk from any client side interface can be assigned at VT/VC-12 and STS/VC-3 granularities. Any client side payload data can be mapped into any legal combination of VT1.5/VC-12, STS-1/VC-3 or STS-Nc/VC-4-Xc positions of the SONET/SDH payload.

The MSF15 performs all SONET/SDH section and line terminating functions including normal or enhanced framing, scrambling/descrambling, parity generation and monitoring, remote line error indication processing, section trace message generation and extraction, orderwire and user channel insertion and extraction. Serial insertion and extraction of all section and line data communication channels, and synchronization message insertion and extraction is also supported. Linear line protection schemes are supported by performing error detection, signal degrade or failure detection based on provisionable bit error rate thresholds, and automatic protection switching information extraction and validation. Line status is consolidated and presented to software in a manner that facilitates rapid identification of faults.

The MSF15 supports full SONET/SDH pointer processing of any combination of STS-1/VC-3 and concatenated payloads up to 155 Mbps. Path overhead monitoring and automatic detection of path level defects for UPSR/SNCP operation, and path trace message generation and monitoring are provided.

Packet mapping, with static or dynamic bandwidth allocation, is supported for one Gigabit Ethernet and up to eight 10/100 Mbps Ethernet SMII interfaces. Packets encapsulated using GFP, X.86 LAPS or RFC1662 PPP are mapped to a SONET/SDH transport payload. Backpressure on the Ethernet ports is implemented with IEEE 802.3x flow control with programmable trigger thresholds. The Ethernet interfaces provide all necessary counters to support SNMP and MIB-II implementations.

Virtual Concatenation (VC) with LCAS is supported on the Ethernet interfaces and provides 8 virtual concatenation groups (VCGs). A total of up to 3 high order member paths (STS-1/VC-3, STS-3c/VC-4) or up to 84/63 low order member paths (VT1.5/VC-12) is available across all VCGs. An internal buffer supports differential delay compensation of up to 4.6 msec, while an external SDRAM interface is used to provide differential delay up to 250 msec.

Up to 28/21 DS1/E1s can be directly connected from external Line Interface Units (LIUs) and either mapped into VT1.5/VC-12s or, via M13/E13, into a DS3/E3 and then into an STS-1/VC-3 path. DS1/E1 framers are provided in both directions to allow full fault isolation on asynchronously mapped VT/VCs. On DS1 interfaces, the Super Frame (SF), Extended Super Frame (ESF) and SLC-96 framing formats are supported, while E1 interfaces support G.704 basic and CRC-4 framing formats with full performance monitoring, and line and facility loopback, test pattern generation.

Up to 2 DS3/E3s can also be mapped into any available STS-1/VC-3. Full performance monitoring is provided in both DS3/E3 framers.
