• "Telephone number": telephone number dialled when connecting to the IAP.
- "Secondary telephone number (backup)" : it may or may not exist depending on the access pro-
vider used.. This number is dialled if the main telephone number is not available..
- Bandwidth
The allocated bandwidth corresponds to the throughput between Alcatel OmniPCX Office and the
access provider for an ISDN type connection. . The bigger the bandwidth, the faster the throughput
(connection costs will be higher in turn). Three choices are possible in the number of B channels
used:
• "1 64 Kbps B channel": a single B channel is used statically.
• "2 128 Kbps B channels": two B channels are used statically. In this case, call charges are mul-
tiplied by two.
- "on demand (64-128 Kbits/s)": two B channels are used dynamically. The charges are identical
to those applied to 128 Kbits/s, but the traffic is optimised to the bandwidth requirements. The
throughput to the IAP must correspond to a 128 Kbps access. This option must not be chosen
if the connection to the access provider is 64 Kbits/s.
- Type de connection
The type of link between Alcatel OmniPCX Office and the access supplier can be established with:
• “On demand call”: the B channel(s) is (are) active in relation to user requests, and is (are) closed
down when there is no more traffic. This type of connection avoids charges when there is no
traffic.
• "Permanent": the connection between the IAP and Alcatel OmniPCX Office is permanent, it is
like using a leased line from the telephone operator..
- "Callback": this option is chosen when a client terminal outside the LAN wishes to access Alcatel
OmniPCX Office via Internet (See Section VPN). It allows Alcatel OmniPCX Office to dial auto-
matically the call number of the IAP in order to establish connection.
- IP address allocation
The IP address is allocated to Alcatel OmniPCX Office by the access provider. This address is public.
If the access provider manages the IP address negotiation, the “dynamic” option must be checked,
otherwise enter the assigned IP address. A fixed IP address is required in the case of a permanent
connection and in order to use a VPN.
- DNS servers
This information corresponds to the IP addresses of the DNS servers on the premises of the access
provider. These servers are used to translate site names into IP addresses.
• "Address of primary DNS server”".
- “Address of secondary DNS server”.
- Connection protocol
