Table 59: CTP Bundle Runtime State and Counters in the CTP Menu (continued)
Field DescriptionField Name
Displays the current configuration of the port:
•
T1LoSCheck—Denotes that LOS detection is specified on a T1 port connected to a CTP bundle or a
SAToP bundle
•
E1LoSCheck—Denotes that LOS detection is specified on a E1 port connected to a CTP bundle or a
SAToP bundle
•
NoRdReclk flag—Signifies that the redundancy receiving (RX) clock is disabled. The NoRdReclk flag
is also displayed because this flag is default enabled for a T1/E1 port, whereas it is usually not enabled
for a serial port.
When you run the bundle query for CTP bundles and SAToP bundles, the T1E1 port type displays port
configuration flags that are relevant to a T1E1 port.
Port Config Flags
Displays the framing type for T1 interfaces.
•
ESF
•
D4
Framing type
Displays the configured redundancy mode.
•
Disable—Y-cable redundancy is not enabled on this port.
•
eXclusive OR (XOR)—Redundancy is enabled. In this mode the Y cable is active only if the port is in
RUNNING state and the serial port on the Y-cable link is not in RUNNING state. If both bundles are
RUNNING, the Y cable remains inactive on both the ports.
•
ReVeRT (RVRT)—When you select this mode, a primary and a secondary path is enabled. The primary
path drives the cable when its bundle is in RUNNING state, independent of the state of the secondary
path. The secondary path is activated when the primary path is offline. Whenever the primary path
comes back online, the path is switched back to the primary path.
•
NOnReVert (NORV)—When you select this mode, the circuit is not switched back to primary when
the primary path comes back online after switching to secondary path. The circuit is switched to the
primary path only when the secondary path fails.
•
Signal (SIG)—The primary path is activated only if the secondary CTS output is inactive. When CTS
is active, secondary drives cable.
Redundancy Config
Specifies whether it is a primary and a backup bundle. When the software link is enabled and link partners
are specified, the software verifies that there is a matched primary and backup pair.
Primary/Secondary
Specifies the link types for primary and back up bundle.
•
H/W link—When enabled, the Y-cable redundancy is supported only on serial ports, and the link
between ports is a hardware signaling connection over a special Y cable that uses the output to
cable(TM) and the input from cable(RL) to communicate redundancy state between port pairs, by
using keepalive pulses. Its operation is similar to the default operation of the redundancy feature in
CTPOS Release 6.5 and earlier.
•
S/W link—Allows Y-cable port pairs to maintain contact with each other by means of OAM packets
instead of using a hardware signaling path. The software link has the following advantages:
•
The software link does not require a special signaling hardware, which means that Y-cable
redundancy is supported on T1E1 ports as well as serial ports with a special Y cable. Serial ports can
get TM/RL signals for user applications.
•
Software or OAM link packets can check link partners and identify configuration errors. They can
also differentiate between dead and alive states.
Pri/Sec Link Type
Specifies an IP address for the other port of the redundant primary and backup pair.IP Address
