You are planning a branch location that requires Tl/El Public Switched Telephone Network (PSTN) trunks. There will be a peak hour usage of 1 PSTN trunk for every 20 of the 500 users. How many PSTN trunks and DSP resources will be needed to support calls between IP telephones and the PSTN in the branch?

  1. 31 PSTN trunks and 32 DSP resources
  2. 25 PSTN trunks and no DSP resources
  3. 25 PSTN trunks and 25 DSP resources
  4. 26 PSTN trunks and 27 DSP resources

Answer(s): A



You are designing media gateways at remote locations for a customer. They have requested the following:
-Analog telephone calls go through the PSTN in case of power outage.
-Redundant power supply
-The same administrative and telephone functionality during WAN outage Which design meets these customer requests?

  1. A design with G450 gateways with dual power supplies, and Standard Local Survivability
    A design with G430 gateways with dual power supplies, and Standard Local Survivability
  2. A design with G450 gateways with dual power supplies, and S8300 Survivable-Remote
  3. A design with G430 gateways with dual power supply, and S8300 Survivable-Remote

Answer(s): A



You are working on a solution design for an Avaya Aura® 8.1 solution and estimating how many Digital Signaling Processor (DSP) resources will be needed.
Which two types of calls require DSP resources? (Choose two.)

  1. H.323 to H.323 calls
  2. ad hoc conference calls
  3. SIP to H.323 station calls
  4. SIP to SIP calls

Answer(s): C



For an Avaya Aura® Communication Manager (CM) 7 Duplex Server hardware solution, what are two capabilities/requirements? (Choose two.)

  1. Utility Server and Services Access Link (SAL) are required to be installed with both CM instances.
  2. The duplex servers provide protection for both hardware and software server faults.
  3. The duplex servers must run in an active-active mode for instantaneous failover.
  4. Identical Servers are required.

Answer(s): D



On an Avaya Aura® 7.x deployment with shuffling turned on within Communication Manager (CM),

which statement describes the media processing resources or Digital Signaling Processor (DSP) requirements for a SIP-SIP two-party call between endpoints using the same codec?

  1. This call will shuffle after initial call set-up; i.e., one media-processing (DSP) channel is required for the first 20 seconds of the call, for each party.
  2. This call cannot shuffle, and two media-processing (DSP) channels are required for the entire call duration.
  3. SIP-SIP two-party calls will use SIP Direct Media, so no media-processing (DSP) channels are required for this call.
  4. SIP-SIP multi-party calls do not shuffle, and after setup use one media processing (DSP) channel for the entire call..

Answer(s): A
