FEATURES

• Integrates 28 T1 framers, 21 E1 framers an d 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 (using the serial clock and data or H-MVIP system interfaces).

• DS3 M13 Multiple xer wit h ingress or

egress per link monitoring.

• Unchannelized DS3 framer mode

for access to the entire DS3 payload.

• Supports transfer of PCM data to/from

1.544 MHz and 2.048 MHz serial interface system-side devices. Also supports a fractional T1 or E1 system interface with independent ingress/ egress Nx64 Kbps rates. Supports a

2.048 MHz system-side interface for T1 mode without external clock gapping.

• Supports 8 Mbps H-MVIP on the system interface for all T1 or E1 links, a separate 8 Mbps H-MVIP system interface for all T1 or E1 CAS channels and a separate 8 Mbps 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.

• Also provides PRBS generators and detectors on each tributary for error testing at DS1, E1 and NxDS0 ra tes as recommended in ITU-T O.151 and O.152.

• Provides robbed bit signaling extraction and insertion on a per-DS0 basis.

• Provides programmable idle code substitution, data and sign inversion, and digital milli watt cod e inse rtio n on a per-DS0 basi s.

• Supports the M 23 a nd C-bi t parity D S3 formats.

• Standalone unc hannelized DS3 framer mode for access to the entire DS3 payload.

• When configured to operate as a DS3 Framer, gapped transmit and receive clocks can be optionally generated for interface to link layer devices which only need access to payload data bits.

• DS3 Transmit clock source can be selected from either an external oscillator or from the recei ve side clo ck (loop-timed).

• Register level compatibility with the PM4388 TOCTL Octal T1 Framer, the PM6388 EOCTL Octal E1 Framer, the PM4351 COMET E1/T1 transceiver and the PM8313 D3MX M13 Multiplexer/Demultiplexer.
