Information Elements 4-66Issue 6 June 1997 Status Bits:When the In-use, Idle, Maintenance-busy, and Other-unavailable status bits are set to 1, a binary-encoded count corresponding to that status follows. Counts:Bytes 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). Later bytes convey the counts for the next highest order status bit set to 1. NOTE: Bytes 5 through 8 are extended to accommodate counts greater than 128. The ECS typically returns counts for the resources in use and the idle resources. The adjunct may sum these two counts to calculate the resources in service. Refer to the DEFINITY Enterprise Communications Server Administration and Feature Descriptions, 555-230-522, for specifics on the ECS running ASAI to determine the maximum values for the parameters encoded in the Value field. This determines the maximum number of bytes used to encode the information. This number varies from ECS to ECS. Hosts should operate with the maximum values for the largest ECS on which they will be running.

Information Elements 4-70Issue 6 June 1997 Status The Status IE: nSupplies information for activating/deactivating Message Waiting Lamps nReturns the status of the Message Waiting Lamp and messaging services supported by the ECS nReturns the ON/OFF status of other ECS features such as Send-All-Calls and Call Forwarding Figure 4-38 shows the format of the Status information element. Figure 4-38. Status Information Element Type of Status (byte 3, bit 7-1) ON/OFF or ASAI (byte 4, bit 5) In all Set Value and Feature Activation/De-activation requests, this bit contains an on/off indicator. In responses to feature status queries, this bit carries an ON/OFF indicator for Forwarding and Send-All-Calls responses. In the response to the MWL query, it indicates whether an ASAI adjunct has turned the MWL on. Thus, in the response to the MWL query, the adjunct must logically OR bits 1-5 in octet 4 8 7654321 Status 0 1001111Octet1 Information element identifier Length of Status contents 2 1 Type of Status 3 Ext 100ON/OFF LWC PMS AUDIXAP/ 4 Ext Spare ASAI MCS Bits 7 6 5 4 3 2 1 0 0 0 0 0 0 0 Reserved 0 0 0 0 0 0 1 Reserved 0 0 0 0 0 1 0 Message Waiting Indicator Status 0 0 0 0 1 0 0 Send-All-Calls Status 0 0 0 1 0 0 0 Call Forwarding Status
