PM4328 TECT3
HIGH DENSITY T1/E1 FRAMER
AND M13 MULTIPLEXER
1 FEATURES
· Integrates 28 T1 framers, 21 E1 framers and a full featured M13 multiplexer
with DS3 framer in a single monolithic device for terminating DS3 multiplexed
T1 or E1 streams.
· Four fundamental modes of operation:
· Up to 28 T1 streams M13 multiplexed into a serial DS3.
· 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 H-MVIP system interfaces.
· DS3 M13 Multiplexer with ingress or egress per link monitoring.
· Unchannelized DS3 framer mode for access to the entire DS3 payload.
· Supports transfer of PCM data to/from 1.544MHz and 2.048MHz serial
interface system-side devices. Also supports a fractional T1 or E1 system
interface with independent ingress/egress Nx64Kb/s rates. Supports a 2.048
MHz system-side interface for T1 mode without external clock gapping.
· Supports 8Mb/s H-MVIP on the system interface for all T1 or E1 links, a
separate 8Mb/s H-MVIP system interface for all T1 or E1 CAS channels and
a separate 8Mb/s H-MVIP system interface for all T1 or E1 CCS and
V5.1/V5.2 channels.
· Supports a byte serial Scaleable Bandwidth Interconnect (SBI) bus interface
for high density system side device interconnection of up to 84 T1 streams or
3 DS3 streams.
· Provides jitter attenuation in the T1 or E1 receive and transmit directions.
· Provides two independent de-jittered T1 or E1 recovered clocks for system
timing and redundancy.
· Provides per-DS0 line loopback and per link diagnostic and line loopbacks.
· Provides an on-board programmable binary sequence generator and detector
for error testing at DS3 rates. Includes support for patterns recommended in
ITU-T O.151.
