Applicability To France - Avaya Nortel Communication Server 1000 Reference

NTAK10 2.0 Mb DTI card

Applicability to France

Features specific to DTI requirements for France are implemented in firmware, and are switch-
accessed. These are:
• transmission and reception of alarm indication signaling (AIS) in TS16 such as card
disabled and warm SYSLOAD
• France-specific PPM counting
• decadic dialing
• France-specific alarm report and error handling
Architecture
The main functional blocks of the NTAK10 card architecture include:
• DS-30X interface
• signaling interface
• three microprocessors
• digital pad
• Card-LAN interface
• carrier interface
• clock controller interface
DS-30X interface
The NTAK10 card interfaces to one DS-30X bus which contains 32 byte-interleaved timeslots
operating at 2.56 Mb. Each timeslot contains 10 bits in a 10 message format; eight are assigned
to voice/data (64 Kbps), one to signaling (8 Kbps), and one is a data valid bit (8 Kbps).
Transmit data
To transmit data on the carrier, the incoming serial bit stream from the NTAK02 circuit card is
converted to 8-bit parallel bytes. The signaling bits are extracted by the signaling interface
circuitry.
Digital Pad: The parallel data is presented to the pad PROM. The PROM contains pad values,
idle code, and A/µ-law conversion. They can be set independently for incoming and outgoing
