Configuring Signaling for CTP Bundles (CTPView)

date_range 28-Jan-20

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. When two or more leads are configured for demand, all configured leads must be in the Demand Call – Active state for the circuit 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:

Log in to the CTPView software at least at the Net_Admin level.
Connect the CTPView server to the CTP device for which you want to configure bundles.

To configure signaling for CTP bundles using CTPView:

In the side pane, select Bundle > Configuration.
Run your mouse over the Display and Select an Existing Bundle bar.
In the table of bundles, select the bundle that you want to modify.
Under Bundle Options, select Advanced Options Show to display advanced parameters and configure the parameters as described in Table 17.
Click Click to Submit Bundle AND Port Changes.
