QUESTION NO: 11 DRAG DROP
Exhibit See Full Version.
Answer:
The one thing that distinguishes a PRI from other interfaces is the fact that the data that is received from the PSTN on the D-channel and needs to be carried in its raw form back to the Cisco CallManager to be processed. The gateway does not process or change this signalling data, it simply passes it onto the Cisco CallManager through TCP port 2428. The gateway is still responsible for the termination of the Layer 2 data. That means that all the Q.921 data-link layer connection protocols are terminated on the gateway, but everything above that (Q.931 network layer data and beyond) is passed onto the Cisco CallManager. This also means that the gateway does not bring up the D-channel unless it can communicate with Cisco CallManager to backhaul the Q.931 messages contained in the D-channel. http://www.cisco.com/en/US/tech/tk1077/technologies_tech_note09186a00801da84e.shtml

A. The T1 PRI controller supports either en-bloc or digit-by-digit formats natively.
B. The serial interface that is associated with the T1 controller needs to include the isdn incoming-voice command.
C. The T1 controller needs to include the isdn overlap-receiving command.

QUESTION NO: 1
What is the function of class-based marking?
A. Marking packets is based only on CoS value, IP precedence value or DSCP value allows Layer 3 frames to be identified and distinguished from other packets.
B. Marking frames based only on CoS value or IP precedence value allows Layer 2 frames to be identified and distinguished from other frames.
C. Marking frames or packets sets information in the Layer 2 and Layer 3 headers of a packet so that the frame or packet can be identified and distinguished from other frames or packets in the same traffic flow.
D. Marking frames only sets information in the Layer 2 headers of a frame so that the frame can be identified and distinguished from other packets or frames.
E. Marking allows network devices to classify a packet or frame, based on a specific traffic descriptor.
Answer: E

[Torrent] CIPT2 – Implementing Cisco Unified Communications IP Telephony Part 2 v8.0

Cisco Course v8.0 | Cisco Unified Communications Manager Software v8.0 | Prepares you for Cisco Exam 642-457 CIPT2 v8.0.

This hands-on course focuses on advanced installation and configuration of Cisco Unified Communications Manager (CUCM) v7 and v8 in global, multisite networks. You will learn how to build the system from scratch to provide:

  • A variable-length on-net dial plan supporting overlapping extensions, as described in Cisco’s Unified Communications System Release 8.x SRND
  • Remote site survivability (SRST and SRST with CME) bandwidth management
  • Mobility features, such as device mobility and extension mobility, used in networks with multiple sites
  • Survivability for remote sites during WAN failure
  • Automated alternate routing (AAR) to deliver calls over the public switched telephone network (PSTN) if no bandwidth is available
