2.4 JT-Q2210

Ericsson SS7 MTP-L3 TTC version R1 is compliant with TTC JT-Q2210 except for the deviations from TTC JT-Q704 (see Section 2.2).

3 Notes and Comments

Note 1		Link groups not supported.

Note 2		Automatic allocation or reconfiguration of signaling equipment is not supported.

Note 3		See the notes for the individual signaling network management messages (clause 15).

Note 4		No difference between long- and short-term processor outage. All emergency changeovers are treated as being initiated by a long-term processor outage.

Note 5		The following timers are not implemented: T7, T9, T11, T24.

Note 6		Timer T24 not used. Signaling traffic management commences without interruptions.

Note 7		Priorities are not set on a per linkset basis, instead priorities are set on routes in routesets.

Note 8		The spare bits are sent transparently to/from the User Part and they are always used as priority bits.
