Collect Call Blocking for E1-R2 and LCO in Brazil
When the E1R2 or LCO receives the incoming collect call, it could reject to accept the call by
operating collect call blocking procedure.
There are two kinds of collect call service types. One is "Without Indicator" and the other is
"With Indicator". For LCO, only "Without Indicator" is available from PSTN network. For
E1-R2, "Without Indicator" is operated with E1 line signaling and "With Indicator" is operated
with R2MFC signaling.
Operation
To activate (deactivate) collect call blocking feature.
Set Admin to activate collect call blocking enabled (disabled). When the incoming call
receives and answers. If activated, as soon as answering, it sends the collect call blocking
signal towards the PX.
Conditions
• When the incoming party sends the collect call blocking signal towards the PX, if it is a
collect call, it disconnects the call. If it is a normal call, it continues to communicate.
• For LCO, to activate collect call blocking feature, set PGM186-FLEX17 to 1 (Without
Indicator) or 2 (With Indicator). For both settings, it works as "Without Indicator" mode.
• For LCO, to block collect calls, loop open is made for "Collect Call Break Timer" after
answering during "Collect Call Make Timer".
