Select IRIG-B.Specifies that the bundle will run in IRIG-B mode.Multi-Service
Mode
Select one:
•
TX (signal enters CTP)—The end
of the circuit that accepts IP
packets, extracts the IRIG-B data
codes, and transmits IRIG-B
signaling output onto the cable.
•
RX (signal exits CTP)—The end of
the circuit that recovers IRIG-B
from the attached cable and
generates IP packets toward the
network.
Specifies the direction of the circuit. Although the IP circuit connection
through the network is full duplex, an IRIG-B circuit is a simplex
application, and the interface can operate only in Rx or Tx mode and
not both at the same time.
(Although the bundle is by default a full duplex IP connection, you
can configure it for simplex to save network bandwidth.)
If the autonegotiation setting of the CTP Ethernet media and the
far-end switch or router do not match, it is possible for the CTP
Ethernet ports to be in a half-duplex state, although the duplex setting
is not configurable and always assumed to be full-duplex on the CTP
device. Starting with CTPOS Release 7.2, the half-duplex state at CTP
network interface card (NIC) ports are acquired, regardless of the
duplex setting configured on the far-end node. After the
autonegotiation process is completed, if the CTP NIC cannot acquire
full-duplex mode, then the interfaces are considered to be down and
a log message is recorded in both the /var/log/messages directory
and the syslog file stating that the interface is down due to a non-full
duplex condition. You are prompted to verify the cable connection,
speed, and duplex settings because the NIC link might be down.
IRIG-B Source
Enter a number from 1000 through
25,500 bps. The port speed must be
a multiple of 100 bps.
Specifies the data rate on the IP connection.
Note the following about setting the IRIG rate:
•
Unless network bandwidth is at a premium, we do not recommend
that you change this value from the default of 16,000 bps.
•
Although the IRIG information can be transported through the
network at the minimum configured rate (1000 bps), a CTP bundle
running at this rate is subject to high latency.
IRIG-B Data
Rate
Enter a number from 0.00 through
7.85 volts peak-to-peak.
This option appears only if you set the direction of the port to Tx.
Specifies the high output level, which is measured in peak-to-peak
voltage. This setting is based on a 50-ohm termination
Output High
Volts Level
Enter a number from 0.00 through
7.85 volts peak-to-peak.
This option appears only if you set the direction of the port to Tx.
Specifies the low output level, which is measured in peak-to-peak
voltage. This setting is based on a 50-ohm termination.
