Explanation
Specifies the E1 channel associated signaling (CAS) protocol that is used
by channels in this group. This parameter is not used with common channel
signaling (CCS).
Note: UK Tie/DDI can also be used whenever “inverted” E&M/US
(also known as European E&M) signaling is required. Because it is not
possible to select Wink Start for the UK Tie/DDI Start Type parameter when
required, wink start operation can be simulated by setting UK Tie/DDI Start
Type to Delay Start, provided the default values are used for Delay Start
Delay and Delay Start Duration.
