Lucent Technologies Release 8.2 manual DCS Over ISDN-PRI, LWC considerations, Busy/Warning

Distributed Communications System		B Private Networking
DCS Over ISDN-PRI	• The gateway node serves as the terminating node to the D-channel DCS network

D-channel	as well as the terminating node to the traditional DCS network.
considerations
	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 DCS network, (BX.25 processor channel links) Remote
	Port in the “Processor Channel Assignments” form refers to the processor
	channel of the destination PBX. In an Integrated DCS network, Remote Proc
	Chan in the “Processor Channel Assignments” form refers to the processor
	channel of the Gateway PBX (if the destination PBX is an ISDN DCS PBX), not
	the destination PBX.
	On the contrary, Machine-IDin the “Processor Channel Assignments” form
	refers to the destination PBX, either an ISDN DCS PBX or a traditional DCS
	PBX. The Gateway PBX number must not be used in this field if the destination
	PBX is an ISDN DCS PBX.
Enhanced DCS	• If the DCS link fails, the administrator can choose to allow calls to continue
considerations	without class of restriction checking or to block all DCS calls to inward-restricted
	stations.
LWC considerations	• LWC cannot be successfully activated toward any system that is not capable of
	storing the messages, either internally or in an associated adjunct.
	• Messages from one node, through an intermediate node, to a remote node do not
	require storage capability at the intermediate node.
	• LWC transparency is supported for all DCS configurations except for cases when
	either the activating node or the remote node is either an ENHANCED
	DIMENSION PBX or a System 85 R2V1.
	• Retrieval of LWC messages is permitted only from a terminal at the node where
	the messages are stored.
	• DCS LWC cannot be activated from an attendant console.
Trunk Group	• Trunk Group Busy and Trunk Group Warning Indication is particularly useful
Busy/Warning	with the Attendant Control of Trunk Group Access feature. The indicators alert
Indication
	the attendant when control of access to local and remote trunk groups is necessary.
