How to administer DCS 
Over ISDN-PRI 
D-channel
Note:There are several differences in administration between switches. 
For example, PRI is translated a little differently in G3r when 
traditional DCS and this feature are used in combination. On 
systems with AUDIX in a DCS environment, an additional column 
has been added to the Signaling Group form so you can...

NCA-TSC
An NCA-TSC is a connection not related with any ISDN B-channel connections. 
DECINITY ECS supports two types of NCA-TSC that conform to two different 
protocol standards:
•The QSIG type of NCA-TSC is used for certain QSIG features such as Call 
Completion (Automatic Call Back). This type of NCA-TSC is referred to in the 
QSIG protocol standards as a...

DCS feature considerations
Attendant•If you call an attendant on another switch in the DCS network, your display shows 
the attendant’s name, but does not show the attendant’s extension, instead you see 
a zero where the extension should be.
Alphanumeric Display 
considerations•On outgoing DCS calls, display of the called name may be delayed for a few 
seconds...

DCS Over ISDN-PRI 
D-channel 
considerations•The gateway node serves as the terminating node to the D-channel DCS network 
as well as the terminating node to the traditional DCS network.
A PBX serving as an ISDN DCS Gateway node introduces some interesting 
situations when administering processor channels in an associated traditional DCS 
PBX. In a traditional...

Attendant Display •When both ISDN and DCS display information, or only DCS display information, 
is received, the switch displays the DCS display information in the DCS format. If 
ISDN display information is received, and no DCS display information is 
received, then the ISDN display information displays in the ISDN formats.

•Leave Word Calling Back to Principal
With DCS Call Coverage, a covering user on a different node cannot press their 
LWC button to leave a message for the principal to call the covering user.
•Queuing
DCS Call Coverage interacts with queuing in the following way. If a call is 
queued to a coverage point, such as a queue to a hunt group or an ACD split, and...

•D-channel Backup
In the event of a D-channel switchover (primary to secondary or secondary back 
to primary) in a private network, administered NCA-TSCs that were active are 
assumed to have remained active. Any unacknowledged user-user service requests 
are assumed to be rejected, and administered NCA-TSCs which were in the 
process of being established at...
