UNIVERGE SV8100
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 UNIVERGE SV8100 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 UNIVERGE SV8100 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 UNIVERGE SV8100 tandem system are passed through and supported.
An UNIVERGE SV8100 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 up to eight systems.

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 UNIVERGE SV8100 can have a maximum of 255 codes assigned to distant systems.

Using an UNIVERGE SV8100-to-UNIVERGE SV8100 network, centralized voice mail is not

supported when an Open Numbering Plan is used.
