3.d Rhino OST T1/E1 PCI card Port and Span configurations
The first lines of the zaptel configuration file (comments excluded) will be the span definitions for
T1/E1 interfaces.
A span definition is in this format:
span=(spannum),(timing),(LBO),(framing),(coding)
(see next page for more examples)
Spannum:
Spannum defines the number assigned to the span these definitions apply to. If you only have one
R1T1 card installed you will only have one span (span 1), if there are two single port R1T1 cards
installed you will have two spans (span 1 corresponds to the first port on the first module loaded).
For an example of span numbering please refer to figure 3.
Fig 4. (dimensions in inches)
Timing:
Use '1' if you want to use the circuit as your primary timing source. If '0' is used Asterisk will try
to provide timing to the span (if you were connecting to a Rhino CB24 this would be correct.). If
Asterisk is connected directly to the telco you will want to use '1' to accept timing from them. If
you have multiple spans; set the timing accordingly such as 2, 3, 4, etc.
0: to not use this span as sync source
1: to use as primary sync source
2: to set as secondary and so forth
