Signaling System 7 (SS7)
Configuring an SS7 signaling gateway
APX 8000/MAX TNT/DSLTNT Physical Interface Configuration Guide Preliminary May 9, 2000 18-5
Settings in the SS7-Gateway profile configure the signaling interface. The TAOS unit resets
the signaling link whenever changes are written to the profile.
Following are the parameters (shown with default settings) for configuring the signaling
interface:
[in SS7-GATEWAY]
enabled = no
control-protocol = asgcp
primary-ip-address = 0.0.0.0
primary-tcp-port = 0
secondary-ip-address = 0.0.0.0
secondary-tcp-port = 0
bay-id = ""
system-type = IASCTNT1B
transport-options = { 0 1000 3000 30000 7 6 no }
use-system-ip-address-as-source = yes
Parameter Specifies
Enabled
Enable/disable the interface. When this parameter is set to no (the
default), the interface is disabled. When it is set to yes, the
interface is enabled if the Primary-IP-Address and
Primary-TCP-Port also have valid values. Changing the setting
from yes to no closes the signaling links but does not disconnect
active SS7 calls.
Control-Protocol Control protocol. The asgcp setting enables the unit to terminate
data calls by using ASGCP. The ipdc-0.x (XCOM/Level 3
IPDC) setting enables the unit to terminate voice and data using
IPDC. If only one SS7 license is enabled, the parameter defaults to
that control protocol (asgcp or ipdc-0.x) and cannot be
modified. If both licenses are enabled, the parameter defaults to
asgcp. See “Specifying the SS7 control protocol” on page 18-6
for more information about this parameter.
Primary-IP-Address
Primary-TCP-Port
IP address and TCP port to use for communication with the
primary signaling gateway. These settings are required for SS7
operations.
Secondary-IP-Address
Secondary-TCP-Port
IP address and TCP port to use for communication with a
secondary signaling gateway. These settings are optional. If
specified, the secondary signaling gateway is used only when the
primary gateway is unavailable. The primary and secondary
address and port configurations can point to two Ethernet
interfaces of the same signaling gateway.
Bay-ID This parameter does not apply when Control-Protocol is set to
asgcp. When Control-Protocol is set to ipdc-0.x, the system
sends its value as an ASCII string to the media gateway controller
in the device registration message. The TAOS unit does not
interpret the value. Interpretation on the signaling gateway is
gateway dependent.
