Status BitsWhen the In-use, Idle, Maintenance-busy, and 
Other-unavailable status bits are set to 1, a binary-encoded 
count corresponding to that status follows.
CountsBytes containing counts correlate with the status bits: The 
first count byte conveys the count for the highest order status 
bit set to 1. Typically, this is the “In-use” count, but it could be 
the idle count (for example). Subsequent bytes convey the 
counts for the next highest...

Timeout IntervalThe interval for digit collection (in seconds) 
once DEFINITY ECS has received the first digit 
(0-63 sec). Encode as all zeros if no timeout is 
to be used. 
User Code DataThe user-entered data is encoded in ASCII 
characters. The ECS sends up to 24 bytes of 
user code data (including * and #). 
When the User-Entered Code carries 
information to log in an agent where EAS is 
activated, then the IE contains both the agent’s

Version
The Version IE shown in Figure 4-42 conveys the ASAI protocol version used on a 
specified ASAI link. It may be repeated in the RESTART message to the adjunct in 
the case where the ECS supports multiple versions. The RESTart 
Acknowledgement message can also contain this IE.

The bit-wise OR operation is indicated by a vertical bar “|’’ and the resulting value 
is the bit-wise ORing of the values on either side of the bar. The word “or,” or a 
comma, indicates that the value is one of a list of possible values. 
The occurrence of a question mark (?) in the Byte Value column means that a 
hex-byte value is present.
