Emergency Nurse Practitioner (ENP) Practice Test

What requires special trunk between tandems and the sharing of peace up routing codes?

1. Router to router transfers

2. Trunked radio systems

3. Direct inward dialing

4. E911

The correct answer is: Router to router transfers

The scenario described involves specialized communication needs, particularly around the sharing of routing codes and trunking—elements that are pertinent to telecommunications networks. When considering the needs for trunking between tandems and routing codes, router-to-router transfers are the most relevant. This involves a setup where data is transferred from one router to another, often over a trunk line that can carry multiple signaling pathways and channels. This aligns closely with scenarios where there is complex data handling and communication between network nodes, necessitating clear protocol and code alignment. Trunked radio systems are primarily utilized for dispatch communications and may involve different radio frequencies but do not directly relate to routing codes in the same way that data transfer does. Direct inward dialing pertains to phone systems allowing direct access to internal phone numbers and does not involve the specifics of trunking in a data network context. E911 addresses emergency calling and location services and, while it incorporates elements of routing, doesn’t focus on the trunking aspect between tandems. Thus, the requirements for specialized trunking and routing codes are best met through router-to-router transfers, aligning with how data is managed and directed across telecommunications networks.
