CTP bundles are supported on the Serial Multiservice Interface module. CTP bundles on
Multiservice Interface modules can operate with the following modes:
Audio—Provides single and dual channel audio support for varying quality audio from
8-bit, 8-KHz quality to 8-bit up to 16-bit, 48-KHz quality (CD quality).
4WTO—Provides single and dual channel audio support for 8-bit, 8-KHz quality with
squelch support for radio backhaul. In 4WTO mode, the Multiservice Interface module
is interoperable with 4WTO daughter cards.
IRIG—Enables an interrange instrumentation group time code (IRIG-B) signal to be
transported through an IP network.
TDC—Provides combined time-correlated support for IRIG/NRZ data for telemetry
applications.
Audio mode provides a high-quality audio (CD quality) interface. Audio mode supports
the following features:
One or two simultaneous channels.
Codec sampling rates up to 48 KHz.
Optional μ-law encoding and decoding.
