Routing
● Callback: Specify whether a call should be rejected and followed immediately by a callback.
This prevents unauthorized peers from dialing in. The calling station must use the ISDN
connection’s D channel to transfer the station number and must permit dial-in via HG 1500.
This station number must be configured for the outgoing direction at the PSTN peer.
● V.34 Peer: Specify if a V.34 peer (e.g. a modem) should be accepted.
● V.110 Peer: Specify if a V.110 peer (e.g. GSM) should be accepted.
● Automatic PPP Connection: Specify if the PPP connection should be automatically estab-
lished at system startup.
● Automatic PPP Reconnection: Specify if the PPP connection should be automatically re-
established after a connection cleardown (for example, in the case of ISP access with flat
rate and forced cleardown after 24 hours).
● PPP Default Header: Specify whether the "default header" should be transferred for the
recipient.
● Scripting: Specify if scripting should be active (see also Section 7.4.4.1, "Display Global
PSTN Data").
● Send LCP Echo Request: Specify if an LCP echo request should be sent. This function is
used to check if the connection is still active.
Short Hold:
● Short Hold: Specify if the "Short Hold" operating mode should be activated or deactivated
for the PPP connection. The following entries are only possible when short-hold mode is
active:
– Short Hold Time (sec): Enter the length of time during which no data is transmitted af-
ter which the PPP connection should be cleared down. The permitted value range lies
between 10 and 9999 seconds. The short-hold timer is only triggered by outgoing
packets (HG 1500 to the PSTN peer).
– Short Hold Charge Pulse Analysis: Specify whether short-hold mode should be opti-
mized taking the charge pulse into consideration. Charge pulse analysis is performed
for calls over PPP (evaluation of facility messages with AoC info elements). If the In-
ternet service provider does not supply call charge information, then the default time-
out value is set to 0 seconds.

If callback is enabled, only outgoing connections from this peer are accepted. A
connection cannot be set up if the peer is also a gateway and if callback is also
enabled for this connection because neither of the peers accept incoming con-
nection setup. In the case of a faulty configuration where only callback without
redial is enabled, this can be detected and continuous connection setup can be
suppressed. However, the problem is not detected if redial is enabled.
