VoLTE (SIP+RTP Support)

Voice-over-LTE means that voice iscarried as regular packet data in a

network. This is achieved by using the

IMS network and SIP protocol for voice

signaling.

Analyze the following: Cover full LTE and IMS technologies

Make sure that the new service is operating

correctly (SIP), and that you can easily view

the correlated voice-quality of those calls

Correlate the LTE signaling issues and SIP

issues for problematic calls Perform voice playback or analyze MOS in

order to ensure quality

Use raw data for root-cause analysis or to

report errors to vendors

Detailed analysis for VoLTE calls:

LTE signaling sessions

SIP sessions

SIP caller/caller ID RTP codec used

MOS for the RTP streams

Supported SFP modules for 1 GigE adapter:

Multimode SR (850 nm) Singlemode LR (1310 nm)

1000 Base-T or 10/100/1000 Base-T (copper SFPs)

Supported SFP+ modules for 10GbE adapter:

Multimode SR (850 nm)

Singlemode LR (1310 nm)

The THP has two different capture cards, which can be combined in any way,but no more than two at a time.

D7 (4 x 1 GigE) and D10 (10 GigE)

Minimum sensitivity is -20 dBm for D7, -9 dBm for D10. D7 has four SFP slots, SM/MM and/or copper can be used in any

combination.

D10 has two SFP+ slots, SM/MM only.

Using SM/MM SFPs requires an active link. A passive splitter can be used forthis. A minimum 70/30 split is recommended. We can provide passive optical

splitters if needed. Another way to connect would be via a TAP (built-in, service node mirrors not

recommended due to load regulation).

Physical adapters are mapped as ports by TravelHawk Pro.

In the diagnostics application, 10 Gig adapter 10Gbps

adapter is mapped as port 0...1, and 4 x 1 Gig 1Gbps

adapter is mapped as port 0...3.
