Operation
1. A station of slave system dials the CO TRANSIT-OUT code.
2. The slave system seizes a CO line that is preprogrammed for transmitting the CO TRANSIT-OUT
code to the master system
3. The master system seizes a CO line that is preprogrammed to serve the lend request by the CO
TRANSIT-OUT code.
4. After seizing the PSTN CO line, the master system sends the digit information to PSTN that is
dialed from the station of the slave system.
5. The called user of PSTN receives the ring. The caller and called users can make a conversation,
when the called user is answered.
Condition
1. To use CO transit-out service, the slave system user must dial CO transit-out code. If it press CO
line button, the CO transit-out service doesn’t executed.
2. The station COS of slave system is applied for toll restriction. At the master system, the attendant
must have the CO access authority about the public connection.
3. For CO transit out, any code will be available using NET routing table (PGM 324). But, if there is
a conflict between NET routing table and system numbering plan, system numbering plan has
high priority.
4. If the CO transit-out code is programmed at an entry of the network numbering plan table, then
the type value of this entry must be set to PSTN (ADMIN program 324 – FLEX 1).
5. If the slave system isn’t connected to the master system directly, the CO transit-out code can be
transmitted through other networking systems transparently by setting the ADMIN program 324 –
FLEX 7 at each networking systems.
6. At the master system, the PSTN CO lines are must be set the ADMIN program 322 – FLEX 4.
