bitOriented(3)—Indicates that E1 Channel Associated Signaling is in use.
•
messageOriented(4)—Indicates that Common Channel Signaling is in use either on channel 16 of an E1
link or channel 24 of a T1.
Robbed-Bit Signalling Protocol (linkSignalling)
This variable determines which robbed bit signalling technique is used. The techniques designated OFFICE
are used to simulate the central office site. These allow back to back connection of access servers. This is set
only when the signal mode is robbedBit(2)
