E1 Port Parameters
Introduction This section describes the E1 port parameters in detail. The E1 Port Record contains
parameter values that you use to define operating characteristics for an E1 dual port
digital interface card.
Configuration
Guidelines
Configure an E1 port before configuring a Virtual Port Mapping Record, which maps
a logical timeslot channel (a virtual port) to that port.
E1 Port Record
Parameters
The following parameters are available from the E1 port record.
Port Type
Range: Voice, T1, E1
Default: Null
Description: Specifies the type of port that you are configuring; the parameter
value you input for port type determines the parameters that
appear next.
Boot Type: Changes to this parameter require a Node boot to take effect.
Line Framing Type
Range: E1_CAS, E1_CAS_CRC, E1_CAS_FEBE
Default: E1_CAS
Description: Indicates type of framing the E1circuit uses.
• E1_CAS: Channel Associated Signaling (CAS)
• E1_CAS_CRC: Channel Associated Signaling with CRC
• E1_CAS_FEBE: Channel Associated Signaling with Si = Far
End Bit Error functionality that sends an indication in TS0
that signifies receipt of a SuperFrame with a bad CRC
Line Coding
Range: AMI, HDB3
Default: HDB3
Description: Selects zero suppression technique used on this E1 link.
• AMI: Alternate Mark Inversion (for testing only)
• HDB3: High Density Bipolar 3
