Digital Services
Two examples for digital services are proved as follows:
• IP connectivity DPNSS/QSIG/PRI/BRI
• Homeworking/ Small Office (With IP Office).
IP connectivity DPNSS/QSIG/PRI/BRI
This configuration allows IP connectivity over Private Digital bearer services.
PC’s are networked in order to access shared resources between two locations.
Once routable Inter-site traffic is present, the IPNC will dial and establish the
specified number of bearer channels. The INDEX system will establish the bearer
channels over the configured Digital link. This configuration provides for the
support of VoIP over “bundled” ISDN bearer channels.
The configuration example is divided into two sections:
Section 1: Details the INDeX environment configuration of the IPNC data call
(establishing IP connectivity) for either the Trunk or Subscriber
IPNC channel types (T and S). The (T) configuration is used if
VoIP is to be deployed (this allows User to User messages to be
exchanged between the INDeX systems at call setup). The use of
(S) Type channels is recommended for it simplicity in the absence
of VoIP requirements.
The configuration of the INDeX environment for the VoIP
telephony is detailed in Part 2 VoIP (see page 89).
Section 2: Details the IPNC configuration in support of IP connectivity over
the DPNSS or Qsig. In addition, see Part 2 Voice Over IP on page
89 for the for details of the INDeX VoIP environment configuration
using T or S type IPNC interfaces.

The following considerations should be made when using this configuration:
1. A maximum of 30 channels can be bundled on a single Digital Link
2. The IPNC can be configured for dynamic operation; meaning that in the
absence of Inter-Site IP traffic the link will be idled
3. G711 VoIP compression is not supported for this application
4. Only the LAN1 will be used (LAN cable must be plugged in to Port A on both
IPNCs).
