Features
GENERAL
- This monolithic device integrates:
- 32 T1 framers.
- 32 E1 framers.
- One SONET/SDH VT1.5/VT2/TU11/TU12 bit asynchronous or byte
synchronous mapper.
- One full-featured M13 multiplexer with DS3 framer.
- One SONET/SDH DS3 mapper for terminating DS3-multiplexed T1 streams, SONET/SDH-mapped T1 streams or SONET/SDH-mapped E1 streams.
- The SPE/STS-1 can be programmed for various T1, E1 or DS3 modes of operation.
- Supports a wide range of T1, E1 and J1 framing formats.
- Supports DS3 framing modes such as M23, C-bit parity, and ITU-T Recommendation G.747.
- Stand-alone unchannelized E3 framer mode (ITU-T Rec. G.751 or G.832) for access to the entire E3 payload.
- Flexible line-side and system-side interface support:
- Supports a 19.44-MHz Scaleable Bandwidth Interconnect (SBITM) Interface for high-density line-side device interconnection to
PMC-Sierra's T1/E1 line interface products, including the 8-port PM4323 OCTLIU LT and the 32-port PM4329 HDLIU.
- Provides a 19.44 or 77.76 MHz SONET/SDH Add/Drop Telecom bus interface for seamless connection with PMC-Sierra's SONET/SDH
devices.
- Supports a byte-serial Scaleable Bandwidth Interconnect (SBI) interface at 19.44 MHz or 77.76 MHz for high-density systemside
device interconnection to PMC-Sierra's link layer products.
- Supports 8 Mbit/s H-MVIP system interface for all T1 or E1 links, a separate 8 Mbit/s H-MVIP system interface for all T1/E1 CAS
channels, and a separate 8 Mbit/s H-MVIP system interface for all T1 or E1 CCS and V5.1/V5.2 channels.
- Supports 28 T1 or 21 E1 links in DS3 or SONET/SDH mode and up to 32 T1 or E1 links when using the line-side SBI interface.
- Supports transparent virtual tributaries when the SBI interface is used with a SONET/SDH mapper.
- Supports insertion and extraction of arbitrary rate (e.g. fractional DS3) data streams to and from the SBI bus interface.
|
- Provides jitter attenuation in the T1/E1 tributary receive and transmit directions.
- Provides three independent de-jittered T1 or E1 recovered clocks for system timing and redundancy.
- Provides per-link diagnostic and line loopbacks.
- Provides PRBS generators and detectors at DS3 and E3 rates, and on each tributary for error testing at T1, E1 and NxDS0 rates as
recommended in ITU-T O.151, 0.152.
- Provides a generic eight-bit microprocessor bus interface for configuration, control and status monitoring.
- Provides a standard five-signal P1149.1 JTAG test port for boundary scan board test purposes.
- Feature-rich functional software drivers available with device.
