Using Bundles to Create Logical Configurations for Physical Interfaces, CTP Release 7.3, CTPView Release 7.3
Configuring Signaling for CTP Bundles (CTP Menu)
48
You can set input and output signals for the CTP device. Your settings should be based
on the settings of the user equipment.
Output signals—You can set output signals to a fixed value, or you can set them to
inband so that the output signal state is based on the state of the input signal at the
user equipment. Output signals that you can set vary depending on whether the bundle
is configured as the DTE or the DCE:
DTE output signals:
DTR (data set ready)
RTS (request to send)
LL (local loopback)
RL (remote loopback)
DCE output signals:
DSR (data set ready)
CTS (clear to send)
DCD (data carrier detect)
TM (test mode)
Input signals—You can set the input signals to either unused (ignored) or used to create
a demand circuit. When configured for demand, packets created from the circuit are
transferred across the IP network only when the signal lead is in the specified state for
the circuit to be
Demand Call – Active
demand, all configured leads must be in the
to transfer packets across the IP network.
Input signals that you can set vary depending on whether the bundle is configured as
the DTE or the DCE:
DTE—Input signals are TM, CTS, DSR, DCD.
DCE—Input signals are RL, RTS, DTR, LL.
The input state of each signal lead is encoded once in every transmitted IP packet.
Thus the granularity of the transitions (frequency or changes) that can be transferred
across the network is equal to the packet rate of the circuit.
Before you begin:
Disable the bundle before you modify the bundle options.
To configure signaling for CTP bundles using the CTP Menu:
From the CTP Main Menu, select 1) Bundle Operations.
