Features
The PM8320 TEMUX 84E3 is a 155 Mbit/s multi-channel T1/E1/J1 Framer with integrated VT/TU, DS3/E3 Mappers and M13 Multiplexers.
- This monolithic device integrates:
- 84 T1 framers
- 63 E1 framers
- 3 SPEs worth of SONET/SDH VT1.5/VT2/TU11/TU12 bit asynchronous mappers
- Three full featured M13 multiplexers with DS3/E3 framers
- Three SONET/SDH DS3/E3 mappers* for terminating DS3 multiplexed T1 streams, G.747 multiplexed E1 streams, SONET/SDH mapped T1 streams or SONET/SDH mapped E1 streams
- Each SPE/STS-1 can be independently programmed for various T1, E1, DS3 or E3 modes of operation.
- Supports wide range of T1, E1 and J1 framing formats.
- Supports M23 and C-bit parity DS3 formats.
- Stand-alone unchannelized E3 framer mode (ITU-T Rec. G.751 or G.832) for access to the entire E3 payload.
- SONET/SDH Mappings:
- Maps T1/J1/VC-11 into VT1.5/TU-11/TU-12/TUG-2/TUG-3
- Maps E1/VC-12 into VT2/TU-12/TUG-2/TUG-3
- Maps DS3 to/from AU-3/STS-1 (SONET) or TUG-3/AU-4 (SDH)*
- Maps E3 to/from AU-3/STS-1 (SONET) or TUG-3/AU-4 (SDH)*
- Flexible line side and system side interface support:
- Provides a 19.44 or 77.76 MHz SONET/SDH Add/Drop Telecom bus interface for seamless connection with PMC's SONET/SDH devices.
- Supports a byte-serial Scaleable Bandwidth Interconnect (SBI™) bus interface at either 19.44 or 77.76MHz for system side interconnection to PMC's link layer devices.
- Supports insertion and extraction of arbitrary rate (eg. fractional DS3) data streams to/from the SBI bus interface.
- Support for transparent virtual tributaries when SBI interface is used with SONET/SDH mapper.
- Supports 8 Mbit/s H-MVIP on the system interface for all T1 or E1 links, a separate 8 Mbit/s H-MVIP system interface for all T1 or 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.
- Provides jitter attenuation in the T1/E1 tributary receive and transmit directions.
- Provides three independent 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.
|
- Feature-rich functional software drivers available with device.
- Provides a generic 8-bit microprocessor bus interface for configuration, control and status monitoring.
- Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board test purposes.
|
VOLTAGE
- Low power 1.8 V/3.3 V CMOS technology. All pins are 5 V tolerant.
