To establish a connection between 2 Abilis we must configure
REMABILIS-ID or REMKEY or both.
These parameters act as a filter for request coming from other
Abilis.
When an Abilis tries to establish a connection, it sends to remote
information about its ABILIS-ID and
LOCKEY (if set). These values are checked for every
NPVL present, and in case of match connection can be established. This
procedure must be verified in both directions.

Now the configuration of the VPN is completed.
This mode is useful to configure a VPN between two Abilis when one of them hasn't a static public IP address or is placed behind a router doing NAT/PAT.
Consider an Abilis with a static public IP address and the other one with a dynamic public IP address:
IP address of “Abilis 1” (ABILIS_CPX_1): 217.1.1.1
IP address of “Abilis 2” (ABILIS_CPX_2): dynamic
“ABILIS 1” will be set as SERVER;

Now the configuration of the VPN is completed.
In case of failure of the permanent VPN connection, the Abilis tunnels may be instantaneously switched onto ISDN backup lines.
The following example considers two Abilis placed in remote sides, with a static public IP address and a backup ISDN line each one:
IP address of “Abilis 1” (ABILIS_CPX_1): 217.1.1.1
ISDN line connected to “Abilis 1” (ABILIS_CPX_1): 01234567
IP address of “Abilis 2” (ABILIS_CPX_2): 217.2.2.2

IP configuration of both Abilis remains the same shown in Section 47.3.2, “IP Packet Voice over IP”.
The configuration of ISDN backup is realized in the Back-Up section. Generally, the following fields are used:
SGI: Input calling sub-address.
SGO: Output calling sub-address.
CDO: Output called number (ISDN of remote
side).
SGI and SGO are special
ISDN's fields where users can insert an alphanumeric string. Abilis uses
them as a sort of password to discriminate the backup calls: the field
SGO of local Abilis is “inserted” in
outgoing calls and verified in the SGI field on
remote Abilis and vice versa (the values of SGI and
SGO on both Abilis must mirror each other).
Other interesting parameters are:
RTY: it allows to select the backup calls
repetition rule;
Table 47.3. Rules of call repetition on failure
| Value | Calls repetition rules |
|---|---|
LIN | The time interval between a call attempt and the next
one is fixed and configurable through the parameter
TB |
INC | The time interval between a call attempt and the next
one, is doubled at every attempt, starting with the value
defined in the parameter TB |
US | The abbreviation US stands for
“unattended site”. In this case the S-Link
channel driver activates the following procedure until
success: 1. The driver executes a number of tries equal to
the value of the parameter NRTY: every
TB seconds, or until three consecutive
“link-check” errors occur; 2. The driver makes
8 calls every 15 minutes; 3. The driver makes 4 calls every
1 hour; 4. The driver makes 9 calls every 2 hours; 5. The
driver makes 8 calls every 6 hours; 6. The driver is placed
in the state STOPPED1 or STOPPED2 caused by the last error;
This procedure allows an “automatic recovery”
from critical situations within three days from the first
failure occurrence, afterwards a maintenance intervention is
required. |
NRTY: it specifies the maximum number of
backup call repetitions.
TB: it defines the “base” time
interval that the retry procedure set in RTY uses
to calculate the delay between a call attempt that fails and the
next one.
AC: configures the autoconnection mode
[DOD, NAILED-UP]:
DOD: the B-channel is connected using
dial-on-demand rules.
NAILED-UP: the B-channel is
spontaneously connected at boot, and reconnected in case of drop
for any reason.

Now the configuration of the VPN is completed.
Activating the ART (Abilis Redundant Tunneling) protocol, also named “Double Path”, can increase the reliability of the VPN.
| Tip |
|---|---|
If one path is slower, or slows down up to blockage, the other path stays unaffected. |
| Warning |
|---|---|
When the double path is active the traffic is obviously duplicated: this could be very “dangerous” on pay per use lines! |
The following example considers two Abilis: each one has two different Internet lines with static public IP addresses.
