4WTO Mode
The CTP 4-wire trunk only (4WTO) analog option provides encoding for one or two
analog voice channels into a single CTP IP data stream.
4WTO mode supports the following features:
•
One or two simultaneous channels.
•
Codec sampling rate of 8 KHz.
•
Optional μ-law encoding.
•
Signaling capability with talk squelch.
•
Configurable output level from 0x to 2x.
•
Interoperability with a 4WTO daughter card. Interoperability is supported only on
daughter cards that have firmware revision 4 or later. You enable interoperability in
the 4WTO daughter card configuration by setting MS interwork to enabled.
IRIG Mode
The Multiservice Interface module enables an interrange instrumentation group time
code (IRIG-B) signal to be transported through an IP network. The IRIG-B standard
consists of a family of rate-scaled serial time codes with formats containing up to three
coded expressions or words. The IRIG-B pulse code contains one frame of 100 elements
per second for the time of the year and GPS receiver status. IRIG-B encodes day of year,
hour, minute, and second data on a 1-KHz carrier frequency, with an update rate of once
per second.
