UC Suite, if available.

1.9.2.7 Scenario 7: Open Numbering in OpenScape Business X3/X5/X8 Networks

A internetwork with open numbering can be set up by networking two (or more) communication

systems whose numbering schemes overlap one another (i.e., not unique throughout the

internetwork).

Network Data

– Network-wide voice networking via OpenScape Business

– UC Suite is not supported.

– Every call within a node occurs with an internal call number

– Every call to another node occurs with a node number + an internal number

– Each node must be configured in Expert mode. The Networking wizard is disabled once a

node number for open numbering has been configured.

– Local access to PSTN and ITSP from each node

– No OpenScape Business S is allowed, since the integrated UC Suite does not work together

with open numbering

1.9.2.8 Networking via ISDN

OpenScape Business systems can be networked with one another as well as with HiPath 4000

systems via digital trunks. Both S

as well as S

lines can be used for the connection.

Networking with telecommunication systems from other manufacturers is possible with the multi-

vendor protocol QSIG. The following must be noted when connecting external systems with the

QSIG protocol:

– Check the QSIG variants of the systems involved for compatibility (QSIG V1, also called QSIG

as per the ECMA Standard, and QSIG V2, also called QSIG as per the ISO Standard)

– Compare the feature sets of the relevant systems. This should help to determine to what

extent the theoretically expected scope of functionality, i.e., the intersection of both feature

sets, corresponds to the customer's wishes.
