2.4 ARTI: ASSIGNMENT OF TRUNK APPLICATION DATA
RST (CDN1) Assignment of Restart
0 = Restart Send per Individual Channel
1 = –
2 = –
3 = Restart not Send
HMT (CDN2) When assigning this data, zero (0) should always be entered.
TRCRST (CDN3) Call Restriction by Information transfer rate in Bearer Capability Information Element
0 = No restriction
1 = Data call restriction (Unrestricted digital, Restricted digital and Video data calls are
restricted.)
2 = Speech call restriction (Speech, 3.1 KHz audio and 7KHz audio calls are restricted.)
3-15 = –
TRSRST (CDN4) Call Restriction by Information transfer rate in Bearer Capability Information Element
0 = No restriction
1 = 384 kbps (H0) call is restricted
2 = 1536 kbps (H11)/1920 kbps (H12) call is restricted
3 = 384 kbps and 1536 (H11)/1920 (H12) kbps calls are restricted
4-15 = –
T309LNK (CDN5) Assignment of Timer T309 for Data Link Failure
0 = Layer 2 Alarm with T309 is Disabled
1 = Layer 2 Alarm [Temporary] with T309 is Enabled
2 = Layer 2 Alarm [Permanent] with T309 is Enabled
3 = –
T309CON (CDN6) Assignment of Timer T309 for Layer 1 Failure
0 = Layer 1 Alarm with T309 is Disabled
1 = Layer 1 Alarm [Temporary] with T309 is Enabled
2 = Layer 1 Alarm [Permanent] with T309 is Enabled
3 = –
LLCRST (CDN7) Call restriction by user rate in Low Layer Capability Information Element
0 = No restriction
1-31 = Call which includes this user rate value is restricte d Note 1
Note 1:
User rate value is based on ITU-T Q-931.
DTRT (CDN11) Detection of ALL 1 alarm signal (DTI Layer 1 alarm)
0 = –
1
= Detection of ALL 1 alarm signal as a Layer 1 alarm
TMPRT (CDN12) Temporary Route Information over CCIS
0 = –
1 = In CCIS, the route information can be transferred by the call control messages.
Moreover, the call restriction can be checked referring to this route information.
