ISDN/X.25 gateway
DEFINITY ECS can serve as an interface between PBXs that support the D-channel 
signaling feature and those that do not support this feature. The switch providing this 
interface is known as the ISDN-DCS Gateway node and provides backward 
compatibility to existing traditional DCS networks.
It maintains a mapping between processor channels and Administered NCA-TSCs. 
When a DCS D-channel message arrives on an Administered NCA-TSC acting as a 
gateway, it is converted to a traditional DCS message and sent out through the 
processor channel that has been administered to map to this Administered NCA-TSC. 
Likewise, when a traditional DCS message arrives at the gateway node on a processor 
channel acting as a gateway, it is converted to a DCS D-channel message and sent out 
through the Administered NCA-TSC that has been associated with this processor 
channel on the ISDN Gateway Channel form.
In summary, a gateway is required whenever a transition is being made from BX.25 
signaling to D-channel signaling. When the transition takes place at a switch that sits 
between that part of the network that supports D-channel DCS and that part that does 
not, that switch is an ISDN-DCS Gateway. A DCS network consisting entirely of 
switches that support D-channel DCS never requires an ISDN-DCS Gateway because 
none of the switches require “translation” to/from BX.25.
DCS Over ISDN-PRI D-channel
DCS Over ISDN-PRI D-channel (DCS+) enhances DCS by allowing access to the 
public network for DCS connectivity between DCS switch nodes. With this feature, 
DCS features are no longer restricted to private facilities.
The ISDN-PRI B-channel is used for voice communications, and the ISDN-PRI 
D-channel transports DCS control information. DCS Over ISDN-PRI utilizes the 
Message-Associated User-to-User Information (MA-UUI) and Temporary Signaling 
Connections (TSC) to transport certain DCS control information. MA-UUI allows 
additional user-specific information to be transported along with certain ISDN 
call-control messages.
Note: Use this feature only over DS1/E1 or T1 circuit packs that are 
administered to Country Protocol Option 1, Protocol Version A 
(even in a private network environment) independent of what 
country the system is in.
