HIGH DENSITY T1/E1 FRAMER
AND M13 MULTIPLEXER
1
FEATURES
Sꢀ 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.
Sꢀ Four fundamental modes of operation:
Sꢀ Up to 28 T1 streams M13 multiplexed into a serial DS3.
Sꢀ 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.
Sꢀ DS3 M13 Multiplexer with ingress or egress per link monitoring.
Sꢀ Unchannelized DS3 framer mode for access to the entire DS3 payload.
Sꢀ 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.
Sꢀ 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.
Sꢀ 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.
Sꢀ Provides jitter attenuation in the T1 or E1 receive and transmit directions.
Sꢀ Provides two independent de-jittered T1 or E1 recovered clocks for system
timing and redundancy.
Sꢀ Provides per-DS0 line loopback and per link diagnostic and line loopbacks.
Sꢀ 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.
