QUESTION 24:
A Cisco router is being used as a VOIP gateway to convert analog and digital voice
signals in the Certkiller network. Which two statements are true about analog to
digital conversion of voice signals for use in digital telephony networks? (Select two)
A. The output of the sampling process is a pulse code modulation (PCM) signal.
B. The three required steps in the analog to digital conversion are sampling, quantization,
and encoding.
C. The three required steps in the analog to digital conversion are sampling, encoding,
and compression.
D. The output of the sampling process is a pulse amplitude modulation (PAM) signal.
E. The three required steps in the analog to digital conversion are sampling, quantization,
and compression.
Answer: B, D
Explanation:
Analog to digital conversion steps include these are:
Step 1 Sampling: The analog signal is sampled periodically. The output of the sampling
is a pulse amplitude modulation (PAM) signal.
Step 2 Quantization: The PAM signal is matched to a segmented scale. This scale
measures the amplitude (height) of the PAM signal.
Step 3 Encoding: The matched scale value is represented in binary format.
Step 4 Compression: Optionally, voice samples can be compressed to reduce bandwidth
requirements.
Analog-to-digital conversion is done by digital signal processors (DSPs), which are
located on the voice interface cards. The conversion is needed for calls received on
analog lines, which are then sent out to a packet network or to a digital voice interface.
QUESTION 25:
Many of the Cisco VOIP gateways used in the Certkiller network contain FXS
interfaces. Which statement is true about Foreign Exchange Station (FXS) ports on
a router?
A. The FXS interface connects directly to an IP phone and supplies ring, voltage, and dial
tone.
B. The FXS interface allows an analog connection to be directed at the public switched
telephone network (PSTN’s) central office.
C. The FXS interface connects directly to a standard telephone, fax machine, or similar
device and supplies ring, voltage, and dial tone.
D. The FXS interface connects directly to ISDN voice channels.
E. None of the above.
Answer: C
Explanation:
FXS: The FXS interface connects to analog end systems, such as analog phones or
analog faxes, which on their side use the FXO interface. The router FXS interface
behaves like a PSTN or a PBX, serving phones, answering machines, or fax machines
with line power, ring voltage, and dial tones. If a PBX uses an FXO interface, it can also
connect to a router FXS interface. In this case, the PBX acts like a phone.
QUESTION 26:
VOIP gateways terminate a large of number of analog circuits in the Certkiller
network. What three types of interfaces do voice gateways use to connect to analog
interfaces? (Select three)
A. E1 CCS
B. E&M
C. Serial
D. FXS
E. FXO
F. T1 CAS
Answer: B, D, E

Humph. Someone has to force me to read this post. It’s too big and boring. Brevity is the sister of talent, remember that.

Feedbacks

* “So after 1 yr and a lot of study i finally did it..CCNP
I cleared ONT today with 989/1000. Do not worry – Prepare and use P4S and you are guaranteed a pass.
If you actually KNOW QoS you can almost pass this test on that knowledge alone. Probably 80/10/10 split between QoS/Wireless security/VoIP. Very easy test in my opinion, but then again, I have lots of experience with QoS and VoIP. Cisco ONT class material is all you need for this one.
ONT is the easist exam i have done for CCNP.
So, i am going on to CCDA and CCDP”
* — Mohamad (Oct, 13 2008)
* “Passed!!!! With a 1000/1000.

Make sure you review:

Analog to Digital = (1) Sampling, (2) Quanitization, (3) Coding, & (4) (the optional Compression)

Digital to Analog = 1 Decompression, 2 Decoding, 3 Reconstruction of Analog Signal

& review Queuing Techniques / differences between them

Next … maybe CCIE or CCSP…still need to think about it..

Thanks Pass4sure!!!”
* — Dietmar (Oct, 12 2008)
* “Passed this morning with a 944. All questions but maybe 2 are straight out of P4S.
Got all from the P4S: the drag-and-drops, the SDM Simlet, and the other new citrix simlet.

Now that I’ve renewed my CCNP, I’m off to re-new my CCDP and CCIE written. Let this be a lesson to all you kiddies out there, do NOT let your certs expire, talk about a PITA to renew…”
