| Question ID 12995 | Which two statements about BFCP with Cisco Unified Communications Manager are true?
(Choose two.)
|
| Option A | BFCP is supported only on full SIP networks.
|
| Option B | Cisco Unified Communications Manager allows BFCP only over UDP.
|
| Option C | BFCP is not supported for third-party endpoints.
|
| Option D | BFCP is not supported through Cisco Unified Border Element.
|
| Option E | BFCP is supported between Cisco Unified Communications Manager and a TelePresence MCU.
|
| Correct Answer | A,B |
Explanation Explanation: BFCP configuration tips To enable BFCP in Cisco Unified Communications Manager, check the Allow Presentation Sharing using BFCP check box in the SIP Profile Configuration window. If the check box is unchecked, all BFCP offers will be rejected. By default, the check box is unchecked. BFCP is supported only on full SIP networks. For presentation sharing to work, BFCP must be enabled for all SIP endpoints as well as all SIP lines and SIP trunks between the endpoints. CUCM uses BFCP over user datagram protocol (UDP) in both secure and non-secure BFCP modes.

| Question ID 12996 | In Channel Associated Signaling on a T1 circuit using Extended Super Frame, how many
signaling bits does each T1 timeslot have?
|
| Option A | 1
|
| Option B | 2
|
| Option C | 4
|
| Option D | 12
|
| Option E | 24
|
| Correct Answer | C |
Explanation Explanation: Each T1 channel carries a sequence of frames. These frames consist of 192 bits and an additional bit designated as the framing bit, for a total of 193 bits per frame. Super Frame (SF) groups twelve of these 193 bit frames together and designates the framing bits of the even numbered frames as signaling bits. CAS looks specifically at every sixth frame for the timeslot's or channel's associated signaling information. These bits are commonly referred to as A- and B-bits. Extended super frame (ESF), due to grouping the frames in sets of twenty-four, has four signaling bits per channel or timeslot. These occur in frames 6, 12, 18, and 24 and are called the A-, B-, C-, and D-bits respectively. Reference: http://www.cisco.com/c/en/us/support/docs/voice/digital-cas/22444-t1-cas- ios.html
