PROPRIETARY AND CONFIDENTIAL
· Provides seven 8Mb/s H-MVIP interfaces for synchronous access to all
· Provides a single 8Mb/s H-MVIP interface for common channel signaling
· All links accessed via the H-MVIP interface will be synchronously timed to the
· H-MVIP access for Channel Associated Signaling is available with the
· Compatible with H-MVIP PCM backplanes supporting 8.192 Mbit/s.
Scaleable Bandwidth Interconnect (SBI) Bus:
· Provides a high density byte serial interconnect for all framed and unframed
· External devices can access unframed DS3, framed unchannelized DS3,
· Framed and unframed T1 access can be selected on a per T1 basis.
· Synchronous access for T1 DS0 channels is supported in a locked format
· Channel associated signaling bits for channelized T1 are explicitly identified
· Transmit timing is mastered either by the TECT3 or a layer 2 device
channel associated signaling (CAS) bits for all T1 DS0s or E1 timeslots. The
CAS bits occupy one nibble of every byte on the H-MVIP interfaces and are
repeated over the entire T1 or E1 multi-frame.

available through this interface. In E1 mode timeslots 15, 16 and 31 are
available through this interface.

Scaleable Bandwidth Interconnect bus as an optional replacement for CAS
access over the SBI bus as well as with the H-MVIP data interface. Common
Channel Signaling H-MVIP access is available with the SBI bus, serial PCM
and H-MVIP data interfaces.
