5.14.7. Code Calling - Normal and Multiple Task 
The code calling system (CC or CCM) is accessible throughout the network.
Normal network code calling is only possible with closed numbering schemes,
CCM is also possible with open numbering plans. CCM can also be used
for incoming calls from the exchange.
The MEET-ME function (Waiting before answering) can be used throughout
the network by PSE/PSM. Network-wide call forwarding/ring no answer to
a PSM MEET-ME is possible. With direct incoming calls from the exchange
the required station is called in addition to the PSM (parallel call),
if CF/RNA is configured and if the PSM and the forwarding station are
located in the same node. Answering via analog and tie trunks is not
possible. The attendant console cannot answer. Switching to PS in other
nodes is possible if the waiting station is in a different node. Switching
is not possible, if the PS and the waiting station share the same node
and consultation hold on the same line was carried out.
For the DISPLAY mode, it is necessary that the A-block number also
be transferred. Therefore, this function is only possible via S0 and
S2 in inter-PBX transit traffic. (For CCM, DISPLAY can also be used for
incoming calls from the exchange with S0 and S2 with CorNet-N or CorNet-NQ
protocol.)
Assign the CC in the node in which it is configured, as before.
In all other nodes, from which paging jobs are to be executable, the
paging code CCSN, CCSCD and CCANS or CCMS, CCMSURG and CCMANS is assigned
on DAR=NETW plus destination number.
- Set the system-specific parameters for the CCM in all systems with AMO ZAND.
CHA-ZAND:TYPE=CCM, STNRNG=param, SRCHTN=param, DEL=param, POSTDBSY=param, SRCHONCE=param, ANNINTCC=param, ANNEXTCC=param, AAFTERB=param, ADISPEND=param, SYNCACCM=param, OPENNO=param;
PSM in networks with open numbering plans
In networks with open or mixed numbering plans all search codes, together
with the node code, are signaled to the CCM, e.g. 263212 if 26-3212
is searched and 273421 if 3421 is searched
If the CCM is called
directly (=prefix), the called number must be terminated by '#'.(1)
The own node code is not required for searching for stations within the
system where the CCM is located.
Programming Call forwarding to CCM remains the same: forwarding destination
= paging code.
- Activate the CCM for open numbering plans:
CHA-ZAND:TYPE=CCM, OPENNO=YES;
- The station numbers must be known to the OpenScape 4000, dialed number - to pager
number
conversion is not possible:
CHA-TSCSU:PEN=<ltg-ltu-slot-cct>, DEV=CCM, STNOLEN=0, CONV=NO;
- Enter the routing code of the home node (corr. WABE code OWNNODE) in every PBX:
CHA-ZAND:TYPE=ALLDATA, PNODECD=<ownnode>;
- Program call forwarding to CCM for stations in a network:
ADD-ZIEL:TYPE=FWD, SRCNO=<number>, SI=VOICE, DESTNOF=<key-num>, DTYPE=<diversion type>, CFVAR=<call forwarding variant>;
where key-num= paging code+ ownnode+station number
| (1) | If the function "PSM with open numbering plan" is active, then this is always applicable, even with closed numbering., |
