• Manufacturer Part Number: MT90880B
• Description: TDM to Packet Processors
• Manufacturer: ZARLINK [Zarlink Semiconductor Inc]

The MT9088x family provides structured, synchronous TDM service, operating at the 64 Kbs channel (DS0) level.
The devices exhibit the following general service characteristics:
1. N × 64 Kbs trunking of any group of timeslots into a single “virtual channel connection” or "context"; these
2. Ability to add or delete timeslots from a context in order to support dynamic bandwidth utilization.
3. Provision of a cross-connect service (i.e. contexts coming from several MT9088x devices are capable of being
4. Ability to operate in "master mode" (supplying the timing to the TDM interface), or in "slave mode" (receiving the
5. Local TDM interface, for connection of external resources, e.g. echo cancellers, modem termination, HDLC con-
6. Low latency connection, with end to end delay of less than 0.5 ms, depending on user configuration
timeslots need neither be contiguous nor from the same stream of data
terminated by a single MT9088x device at the far end).
