PM8315 TEMUX
HIGH DENSITY T1/E1 FRAMER WITH
INTEGRATED VT/TU MAPPER AND M13 MUX
1 FEATURES
Integrates 28 T1 framers, 21 E1 framers, a SONET/SDH
VT1.5/VT2/TU11/TU12 bit asynchronous mapper, a full featured M13
multiplexer with DS3 framer, and a SONET/SDH DS3 mapper in a single
monolithic device for terminating DS3 multiplexed T1 streams, SONET/SDH
mapped T1 streams or SONET/SDH mapped E1 streams.
Seven T1 modes of operation:
Up to 28 T1 streams mapped as bit asynchronous VT1.5 virtual tributaries
into a STS-1 SPE or TU-11 tributary units into a STM-1/VC3 or TU-11
tributary units into a TUG3 in a STM-1/VC4.
Single STS-1, AU3 or TUG3 Bit Asynchronous VT1.5 or TU-11 Mapper
with ingress or egress per tributary link monitoring.
Up to 28 T1 streams M13 multiplexed into a serial DS3.
Up to 28 T1 streams M13 multiplexed into a DS3, the DS3 is
asynchronously mapped into a STS-1 SPE.
DS3 M13 Multiplexer with ingress or egress per link monitoring.
Up to 28 DS3 multiplexed T1 streams are mapped as bit asynchronous
VT1.5 virtual tributaries or TU-11 tributary units, providing a
transmultiplexing (“transmux”) function between DS3 and SONET/SDH.
Up to 21 T1 streams mapped as bit asynchronous TU-12 tributary units
into a STM-1/VC3 or TUG3 from a STM-1/VC4.
Three E1 modes of operation:
Up to 21 E1 streams mapped as bit asynchronous VT2 virtual tributaries
into a STS-1 SPE or TU-12 tributary units into a STM-1/VC3 or TUG3
from a STM-1/VC4.
Single STS-1, AU3 or TUG3 Bit Asynchronous VT2 or TU-12 Mapper with
ingress or egress per tributary link monitoring.
Up to 21 E1 streams multiplexed into a DS3 following the ITU-T G.747
recommendation. This E1 mode of operation is restricted to using the
serial clock and data or HMVIP system interfaces.
