●PRODUCT OVERVIEW
●The PM8312 TEMUX 32 device is a 64-Mbit/s multi-channel T1/E1 framer with an integrated VT/TU Mapper and M13 Multiplexer.
●PRODUCT HIGHLIGHTS
●• 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 unchannelized DS-3 or DS3-multiplexed T1/E1 streams.
●• 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 (SBI™) 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 system side 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 mode and up to 32 T1 or E1 links when using the line-side SBI interface or SONET/SDH mode.
● • 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.
