With Call Pickup Network Wide, users must be assigned to the same Call
Pickup group regardless of network location. Each Ringing Number Pickup
Group may be linked to a Speed Call List (SCL) which is used when there is
not an applicable local set to pick up. Different groups may be linked to
different SCLs.
To be able to route calls through the network from one originating node to a
destination node, an ISDN Private Integrated Services Network Exchange
(PINX) DN is defined for each node in the network. The ISDN PINX DN is
a DN taken from the customer's numbering plan used to aid with the routing
of network calls. It does not correspond to a real terminal on the node, so can
never be busy. Each SCL contains a list of PINX DNs which correspond to
the remote nodes or customers to be searched. Thus, the purpose of the Speed
Call List is to let the system know where to look in the network to pick up the
call. If a pickup group is linked to a Speed Call List, this group is considered
as being network wide.
The search is conducted in an ascending order as programmed in the Speed
Call List (i.e., entry 0 first). This Speed Call list is used when there is not an
applicable local set to pick up.
When a network search is performed, a slight delay occurs before a call is
connected or rejected, during which time the set will receive silence. This
delay is traffic dependent. If for any reason the call cannot be rerouted to the
requesting party, the call will ring again at the originally dialed DN and the
requesting party will receive overflow tone.
Operating parameters
A Speed Call List must be configured with the PINX DNs of the remote
switch. The local PINX DN must be configured in the Customer Data Block
(LD15).
If on one single node two calls are ringing at the same time, the call with the
higher priority will be picked up. But if on two nodes two calls are ringing at
the same time (one call on each node), the call on the node searched first will
be picked up (i.e., a normal ringing call on the local node is picked up before
a priority ringing set on a remote node).
