Electra Elite
Features and Specifications Manual
A total of 16 DID(4)-U10 ETUs can be installed in the Electra Elite
¥
192 system. A total of 4 DID(4)-U10 ETUs can be installed in the
Electra Elite 48 system. Each DID(4)-U10 ETU provides connection
circuitry to handle up to four DID lines. The Electra Elite 192 system
is limited to 64 trunks and the Electra Elite 48 system is limited to 16
trunks.
Each port of the DID(4)-U10 ETU can be set to receive DTMF or DP
¥
(10 pps or 20 pps) signaling.
Incoming calls on DID lines follow Call Forward and Station Hunting.
¥
DID calls can be routed to an ACD or UCD Hunt group.
¥
Incoming DID calls can be assigned for voice announcement from
¥
the outside party, system-wide.
Outgoing restriction can be assigned to DID lines, per station, to
¥
prevent access when the line is assigned on a line key.
System Software S4000 or higher allows DIDs to be routed to
¥
specified tenants using Memory Block 1-1-22 (DID Digit
Conversion Table).
When a call is terminated to a tenant, termination indication and
¥
ringing is performed only on telephones in that tenant. On the
telephones in other tenants, the red CO line key LED is on and
ringing is not assigned.
Termination to a tenant can also be specified as the destination for
¥
the Busy Station or Undefined Digits.
DID incoming call termination can also be performed to the
¥
destination in the DID conversion table (Day or Night) according to
the day and night modes for that specified Tenant.
When the number of DID incoming calls is over, a busy signal is sent
¥
to the network. User Busy is displayed when an incoming ISDN call
is refused. The reason is Cause #17.
The following DID calls are counted against the number of total calls:
¥
• A call that is placed on hold, transferred, or conferenced.
• A call received by one Tenant and Transferred to another
Tenant counts against the first Tenant.
• A call that is received and disconnected.
