Signalling. The Acquirer is to provide details on the signaling requirements upon which Call Type is to be delivered. Attachment or reference to the relevant ITU-T Recommendations is required. If a new Call flow signaling sequence is required to support the new Call, this is also to be captured in this section.
Signalling. Automatic absolute block signalling for the main line from Cockburn to Broken Hill, excluding the Crystal Street yard.
Signalling. Signalling arrangements are as specified in the WR plc Safety Case
Signalling. 5.1 In respect of the Telecommunications Services, Mercury and NYNEX shall ensure that their respective signalling arrangements between their respective Systems conform to the UK C7 signalling protocols as defined in Specifications PNO-ISO/Spec/005 Message Transmission Part and PNO-ISC/Spec/006 Interconnect User Part in force at the date hereof
5.2 Signalling links shall be carried in time slot 16 of a Circuit. Each Circuit which is required to carry signalling shall also be capable of conveying Calls.
5.3 Signalling links shall be carried in the first and second Circuit of a Traffic Route.
5.4 One pair of signalling links (always in separate Circuits and over separate physical routes where possible) shall be used for each group of up to 40 Circuits.
5.5 NYNEX and Mercury shall configure and utilise Circuits in a uni-directional manner.
5.6 In the event that the Parties agree to configure a Circuit in a bi-directional manner, either Switch may seize the free traffic channels and one or both Switches shall clear the seizure and re-attempt the Call set-up. Priority on dual seizure shall be given to Mercury. In order to minimise the number of simultaneous traffic seizures, each Switch shall search its traffic channels in the reverse sequence to the other Switch. The NYNEX Switch shall seize channels in ascending order and the Mercury Switch shall seize channels in descending order.
Signalling. Automatic power signalling in Nome-Stuart section.
Signalling. 1.4.1 Chapter 5 of ITU-T Recommendation G.732 shall apply.
Signalling. 3.1. As stated in Clause 12 of the Main Body of this Interconnection Agreement, Signalling protocols used by the Parties shall follow the ITU Signalling System No. 7 standards.
3.2. To achieve the required level of Signalling resilience, a minimum of 2 Signalling links are required for each Signalling link set.
3.3. The Signalling links making up each Signalling link set and the number of 64Kb/s voice channels associated with each Signalling link are represented by the Parties as follows: Signalling link set Signalling link Interconnection Links associated with the Signalling link 64kb/s time slot associated with this Signalling link The above table has been compiled by the Parties for each Interconnection Path between an Operator Interconnection Node and a Vodafone Interconnection Node.
Signalling. Called party number format 10 Digit – 345 NXX NNNN Calling party number format To Be Agreed (TBA) Number length (range) 1-11 Digits Mobile Country Code/Mobile Network Code In accordance with ITU Regulations and/or local numbering administrator on advice of Telcordia
Signalling. Called party number format 10 Digit – 767 NXX XXXX Calling party number format 10 Digit – 767 NXX XXXX Number length (range) 3-18 Digits
Signalling. If Time Slot 16 is not required for signalling information, it must not be used as a traffic carrying channel within the BT System. Signalling across the interface is not specified in this document.
