Signaling Conversion System
V52 Converter
Q. Why do we sometimes counter noise during calls?
A. The card needs to be plugged in so that it seats properly in all the five connectors. Standard procedure for ejection and removal needs to be
followed.
Q. Why is the V5.1 not coming up?
A. The Interface group Identifier on each end of the V5.1 interface (AN and LE) has to be the same.
Q. Will both V5.1interfaces support ISDN?
A. Yes. ISDN C channels can be provisioned on both V5.1 and V5.2 interfaces.
Q. Is there any problem in multiplexing few C-channels from few V5.1 interface into one interface of V5.2?
A. It is possible, CoPCE1600 will be performing the signaling conversion. CoPCE1600 will support V5 Ig concentration
Q. Can the converter support ISDN BRI, generally and in the current configuration?
A.Yes. The converter can support enveloping passing of enveloped ISDN D channels transparently from V5.2 to V5.1 interfaces and vice versa. For a
given ISDN C channel, the number of ISDN BRI interfaces that are multiplexed and the Interface group information on both interface types has to be
configured
Q. What will l need to do to define two V5.1 interfaces so that the users will be mapped to one V5.2 interface?
A. Each V5.1 interface group will have unique interface ID. V5.2 ig will maintain mapping table for V5.1 interface Id and port to V5.2 layer-3 address.
Q. In port 1 we saw in the E1 analyzer that the working mode is of 'double frame' instead of 'multi frame' and we receive zero in timeslots 1 - 31?
A. E1 framing for both V5.1 and V5.2 links should always be
Q. How must I change the configuration so V52 will work with links 3 & 4 of your card?

Tone Generation and Detection FAQsF
Q. Does the V5.2 card have DTMF detection and tone generation for its time slots?
A. Yes, DTMF detection and generation is possible on all the timeslots.
Q. Are the number of tone generators and DTMF detector on the board enough for all time slots on the board with no blocking (one to one)?
A. Theoretically yes. But due to certain additional
sensitivity, talk-off, echo suppression and debouncing ; the effective limit comes to 256 channels, which is half the number of timeslots supported on
the board.
Q. Does the V5.2 card have the resources to send the caller Id info towards the Access Node?
A. Yes.
Q. Can the V5.2 card enable the user application to control the tone generation and the DTMF detection at anytime during the call?
A. Yes, by means of Tone Service APIs
Q
direction).
A. Yes, a timeslot in inward direction can be connected to the DTMF detector and in outward direction (Egress) can be connected to the Tone
generator.
Q. Does the V5.2 card allows the application to compose and send the tones specified in the attached document?
A. Currently, the call progress tones and DTMF/MF-R1R2 Tones generation and detection is supported along with basic call progress tones like
dialtone, ringback tone, busy tone. Special Information Tones are under development.
H.110 FAQ's
Q. Does the V5.2 card enable the user application to connect or disconnect any timeslot to the H.110 bus during anytime of the call?
A. Yes, APIs are provided that can be used by applications developed on the CPU card (under Solaris or Windows OS) to make/delete cross connects
from the V5.1/V5.2 E1 timeslots to timeslots on the backplane H.110 bus.
Q. Is there any blocking in the switching between the time slots and the H.110 bus?
A. CoPCE1600 boards have 16 E1 interfaces. So, 512 timeslots can be handled in the board, including signaling and bearer timeslots. There is
sufficient TDM switching capacity on-board that supports simultaneous connections of upto 512 timeslots to the H.110 TDM bus in non-blocking mode
and full duplex.
Q. Does the
A. There are APIs provided along with the V5.2 software builds for various functions like board administration, V5 configuration, bearer channel
management, Call Control, Performance Monitoring of E1 links, Statistics and Asynchronous notification of Events
Q. We can define multi group interface from the
A. Yes, multiple interface groups can be defined on the same board. The max limit is 8, since each V5.2 interface group needs minimum of 2 E1s. The
limit can be extended to 16 when primary and secondary E1 links are handled on separate boards.
Q. Our application will be running on top of Linux OS not Win NT. Will it work?
A. The standard package includes Linux support only when the APIs are exercised over Ethernet and not PCI bus.
Q. If our user App is one process (multithreaded), will it work?
A. Yes. The user Application however has to bind and register with our lower layers like IPC Manager, which is like an abstraction layer to our system.
Q. Who manages the Q.921 and Q.931 in case of ISDN signaling over V5 protocol?
A. V5 CoPCE1600 board controls the V5.2 signaling and the CoPCE1600 ISDN resource board handles the Layer-2 and all Q.931 layer-3 frames are
exported to host user application for further processing. Here V5 ISDN communication channel is nailed up to H.110 back plane time slot of
CoPCE1600 ISDN resource board which takes care of ISDN Q.931 signaling. The bridging between V5 and ISDN signaling will be done by the user application.
Q. Your V5.2 PSTN only supports establish and disconnect. Does this put a limitation on what the user app can do with it?
A. User Application can now have complete control over PSTN,
