Table 11-6 Assignment of CF Segment for IEEE 1344(C37.118-2005)
To use these extra bits of information, protective
Relays, RTU‟s and other equipment receiving the time
code must be able to decode them.
INFORMATION
In IEEE 1344 C37.118-2005 Leap Second, Leap Second Pending bits are not
supported in this firmware version.

model MTS200 supports different IRIG-B 00x/IRIG-B12x protocols. Supported protocols
are listed below.
a) IRIG-B007
: 100 pps, DCLS Signal, No carrier Frequency
BCDTOY, BCDYR, SBS (Time of Day)
b) IRIG-B127
: 100 pps, AM Signal, 1 KHz carrier Frequency
BCDTOY, BCDYR, SBS (Time of Day)
c) IEEE 1344 (C37.118-2005) : 100 pps, AM Signal, with 1 KHz Carrier frequency

11.2.2.6 Selection/configuration of IRIG-B Time Codes:
The time code generated can be selected/configured using Telnet menu available on model MTS200
Ethernet port NTP1.
IRIG-B time code for model MTS200 can be configured for
1) IEEE 1344 C37.118
– 2005 protocol enabling
2) UTC time on IRIG-B time code or Local time on IRIG-B time code.
IRIG-B DCLS time codes (IRIG-B 00x) and IRIG-B AM time codes (IRIG-B 12x) are always generated
simultaneously. Using telnet if we configure the IRIG-B output for IEEE 1344 protocol than both IRIG-
B00x and IRIG-B12x gives IEEE 1344 protocol CF bits output. Similarly, we can configure IRIG-B output
