Overview
This section includes configuration information specific to the T-ONE line card.
To change the Start Dial Type, use the PPL Configure message to modify the following Config Bytes:
Byte 101 = Incoming Start Dial
Byte 102 = Outgoing Start Dial
To change Transmit Signaling, use the PPL Configure message to modify the following Config Bytes (see the Transmit Signaling Configure message for values).
Byte 111 = Onhook pattern
Byte 112 = Initial Outseize
Byte 113 = Secondary Outseize
Byte 114 = Inseize ACK
Byte 115 = Answer
Byte 116 = Post Outseize ACK
To change Receive Answer Line Signaling, use the PPL Configure message to modify Config Byte 132 (see the Receive Signaling Configure message for values). This byte stores the default answer line signaling for the configured trunk type. It is used to report CPA of answer through line signaling. If a protocol other than the default is used, this byte should be updated to reflect the answer line signaling.
