Compelled—In the compelled mode, the network sends an MF tone to the system to request a digit.

This tone remains on until the system responds with an appropriate tone. When the installer selects

the compelled mode, the system responds to the digit request by sending a digit, or a tone that

indicates no more digits are available. When the network receives the system’s response, it removes

the request tone and the call progresses.

Semi-Compelled

—In the semi-compelled mode, the network sends an MF tone to the system to

request a digit. The MF tone remains on until the system responds with an appropriate tone, or a

network timer expires. When the installer selects the semi-compelled mode, the system responds to

the digit request by sending a digit, or by letting the network time out if no more digits are available.

When the network receives the system’s response or times out, it removes the request tone and the

call progresses.

Pulsed

—In the pulsed mode, the network sends an MF tone to the system to request a digit. It sends

this tone for a short duration and then removes it. When the installer selects the pulsed mode, the

system responds to the digit request by waiting until the tone is removed, and then sending a digit, or

a tone indicating that no more digits are available. When the network receives the response, the call

progresses.

Force Release Time

Is the time period during which a network can release a line before the communications system sets

the line to an idle state. In some locations, the network requires the system to maintain a busy state

on a line when the outside party hangs up. This is to allow the network sufficient time to prepare its

resources for another call. Typically, the network sets the line to an idle state when its resources are

ready and the system responds to this action by also setting the line to an idle state. In these

locations, protocol requires the system to force the line to an idle state if the network does not set the

line to an idle state within a specific time period. If the network does not return the line to an idle

state within the force release time period, the system sets the line to an idle state. The network will

typically respond by setting the line to an idle state, or to an out of service state. If the network sets

the line to an out of service state, the system also sets the line to an out of service state and prevent

further access to the line until the network places the line back in service.

Co-Disconnect Response

Allows the installer to select the station response to a CO disconnect on a DID call. Typically it is

desirable to have a station return to an idle condition when the system receives a positive disconnect

signal from the company this action makes the station immediately available for another call.

However, the Argentina National Network requires that a station receive an audible indication when

the outside party goes on-hook. To meet this requirement, software release 13A adds an option that

allows the installer to select the station response to a CO disconnect on a DID call. One option is to

release the line and have the station return to idle. The other option is to return the station to the

intercom state and give error tone to the station. The station continues to give error tone until it’s

user places it on hook or the intercom mode timer expires.
