Global
Configuration
Settings
Interface Type: T1 = North American T1 1.544 Mb/s
E1 = European E1 2.048 Mb/s
Note: the interface type applies to all spans on the board.
Clocking
Mode: External = T1/E1 clocking is derived from the telco's clock on the T1/E1 span. The gateway attempts to
derive clock from each available span in succession starting with span 1. For example, the gateway first tries to
derive clocking from span 1 and, if that fails, tries span 2, and so on.
Internal = T1/E1 clocking is derived from the internal clock source on the PIKA Digital Gateway PCI board.
This setting is typically used for span-to-span testing of the gateway with a crossover cable.
Number of
Interfaces: The number of licensed interfaces (digital spans) on the board. Values are 1, 2, 3 or 4.
For example, if you have licenses for 60 E1 channels, then Number of Interfaces should be set to 2.
Fax/Modem
Detection:
If enabled, fax detection is enabled for all incoming ISDN calls. The gateway sends a SIP INFO message
indicating that the incoming ISDN call is a fax. For details of the SIP INFO message see Call Analysis SIP
Message Details (pg. 25).
Interface Configuration (Layer 1)
Line Framing
The line framing format of the span interface(s) hosted by this resource group. This parameter, along with
Line Encoding
,
Line
Buildout and Line Compand , defines the physical characteristics of the span(s).
