Electra Elite IPK II Document Revision 4C
K-CCIS – T1 2 - 671

Outgoing CO calls in a K-CCIS network can be routed over the K-CCIS link and use the
distant system CO lines.

Distant system extension numbers in the K-CCIS network can be assigned to Feature
Access or One Touch keys and Speed Dial buffers.

When a K-CCIS trunk is on hold, the Specified Line Seizure access codes can be used to
retrieve the call from its held state.

The Electra Elite IPK II can support only 2~8-digit station numbers.

Station Numbers are assigned by the 10s group for 4-digit station numbers, 100s group for
5-digit station numbers, 1,000s group for 6-digit station numbers, 10,000s group for 7-digit
station numbers.

When Voice Mail Message Waiting status must be sent across the K-CCIS to a remote
system, F-Routes must be used.

For a Closed Numbering Plan network using F-Routes, a maximum of 120 F-Route Tables
are available allowing a maximum of 121 connected systems per K-CCIS network.

When a Closed Numbering Plan Network is used, a user can call another station by dialing
the distant extension number, but extensions in the network cannot have the same prefix.

For an Open Numbering Plan network, a user can dial another station by dialing the office
location number plus an extension number and the extension number can have the same
prefix, but the office location cannot be the same.

When an Electra Elite IPK II system is a tandem system (in the middle) between systems
with higher K-CCIS feature support (including NEAX PBXs), only the K-CCIS features
supported by the Electra Elite IPK II tandem system are passed through and supported.

An Electra Elite IPK II K-CCIS network should never have more than five hops (tandem
connections) because of the message delay through each tandem system.

A Star topology network supports only five systems because of the CCH channels in the
Main/Hub system.

A Tree topology network is supported. The maximum number of systems depends on the
Numbering Plan used and the maximum number of hops (tandem connections).

A Mesh topology network is not supported.

K-CCIS requires assigning a point code for each office. Point codes differentiate between
an originating office and a destination office in the K-CCIS Network. Assigning point codes
requires the following considerations:

The point code must be unique in the network.

When a system has two or more CCH channels, the same originating point code must be
assigned to all channels in the system.

The Electra Elite IPK II can have a maximum of 255 codes assigned to distant systems.

Using an Electra Elite IPK II-to-Electra Elite IPK II network, centralized voice mail is not
supported when an Open Numbering Plan is used.
