Communications systems built to drive business ahead

MD Evolution 8.1

Product News

PN 06:16 Rev A 2006-10-20

Created by ESF/KEP/MA Francois Vaillant

CTA board provides 4 trunks with loop start support. Tone progress detection,

battery reversal detection, decadic (pulse) (66ms / 33ms) or DTMF dialing are

implemented on the CTA board.

Some other features are not available: tax pulse detection, system failure relay,

direct incoming dialing. But the available DISA service is an alternative to DID.

The CTA board interfaces are designed to meet FCC, TBR21, and some

specific country dependant standards (AC termination, DC characteristics, ring

detect and frequency, among others), and fulfill requirements for safety,

immunity, EMC according to EN55022 and EN55024, as well as FCC parts 15

and 68.

Protections against over voltage are included on the CTA boards. The CTA

interfaces can pass UL1950 tests, as well as ITU_T K21 basic level. In case of

strong environment, when it is required to fulfill K21 “enhanced level”,

additional external protections (gas discharge) must be provided.

The CTA consumption is 0.5 W. The MTBF estimate of the CTA board is

roughly 300000 hours.

Services available with the analogue trunks

Except the CLIP service on incoming calls, all other services are already

available with other external lines.

For incoming calls:

- Welcome messages

- CLIP service. Caller ID detection is handled in FSK

mode by four FSK modems located in the DSP on the

CPJ6 board. “On Hook Caller ID” reception (i.e.

during ringing phase) is implemented.

- DISA service

For outgoing calls:

- Toll restriction tables to enable/ disable external

local/international calls

- LCR service

- Call forwarding to external telephone number

- Hot-line extension calling an external telephone

number

For calls in progress:

- End-to-end dialing when calling an external device

asking for DTMF codes

- Flashing to get external services provided either by

the public exchange or by another PBX connected to

the MD Evolution system

- Trunk-to-trunk connection when you want transferring

an external call to another external call
