Field name Description
• Automatic Keypad Enables Automatic Keypad sending i.e. if the first
dialed digit to be sent on this interface is either '*' or
'#' the digits are not sent as called party number, but
as Keypad information instead. This is used on some
ISDN networks for non call related supplementary
services (for example *21No# to set call forwarding).
• Suppress HLC Suppresses the transmission of “high layer
compatibility” information elements on the interface.
See 22.7 Suppression of specific Protocol Elements on
page 156.
• Suppress FTY Suppresses the transmission of “facility information
elements” on the interface. See 22.7 Suppression of
specific Protocol Elements on page 156.
• Suppress Subaddress Suppresses the transmission of “subaddresses” on the
interface.
• Suppress Connected
Num.
No connected number information elements are
transmitted.
• No Restart Suppresses the sending of RESTART messages.
A restart message requests the recipient to: return to
an idle condition, determine if there is a call present
on the channel, terminate each call found, and
respond with an Acknowledgement message.
• Passive Layer2 Normally the device tries to establish the link layer on
point to point interfaces as soon as the physical layer
is established. This behaviour is especially
incompatible to some ISDN conformance test
equipment even if it conforms to standard. This
option turns this off.
• No overlap Receive Suppresses a SETUP_ACK on incoming single digit
dialling on a point to multipoint connection, in TE
mode. See 22.6 Single Digit Dialling on Terminals on
Point-to-Multipoint Connections on page 156.
• No Disc If set, incoming calls cannot be rejected (no DISC in
incoming call accepting status. See 21.10 Reject calls
on page 149.
• No Disc for Call Reject Call Rejection is done with REL message instead of
DISC.
• Annex-N Refers to the ETS 300 102 Annex-N. This allows in NT
mode inband tones to be sent on incoming calls
before connect (usually the network does not connect
the B-channel in this state).
• Volume In some cases, it is desirable to adjust the basic
volume level of an interface. The volume of the TEL
interface can be set in the range from -31 to +32. The
units of the volumes setting are Decibels. No entry, or
the value 0 corresponds to the factory setting.
A - entry reduces the volume and a + entry increases
the volume of the associated interface.
