Cordless Voice Module

FINAL

4.11.1 Handling product identities

To secure that the FP and PPs do not make cross-

communications a unique ID must be entered into the

VES of an FP or PP. For the DECT version the ID for

the FP is named RFPI and for the PP the ID is named

IPEI. These numbers are factory settings.

After a successful registration, the IPEI is stored in the

FP and the RFPI is stored in the PP. In this way the two

parts are known to each other and are allowed to make

connections. The registration data are automatically

stored in VES of the FP and PP while making the regis-

tration.

It is possible to register the same PP to 2 FPs, but it

can only be used in one FP at the same time.

4.11.2 Deregistration

There are two ways of deregistering a PP from an FP:

• Remote FP and PP deregistration

The correct way to deregister a PP from an FP is to

deregister it remotely in the FP. If this is done over a

service connection from the PP to the FP, the FP

actually performs the deregistration and then it is

automatically signalled to the PP which in turn will

drop out-of-lock. Using this method it is also possible

to deregister other PPs registered to the FP from

one PP.

• Removing all registrations at once from the FP (e.g.

in case the original PPs are lost).

4.12 PCM INTERFACE

The PCM supports the following modes:

• SLAVE mode clock sync. In this mode the clock of

the module will be adjusted to follow the PCM pro-

vided by the external PCM master clock. All audio

samples are kept if the provided PCM clock accu-

racy is +/- 5 ppm, which is a DECT radio require-

ment.

• SLAVE no clock sync. In this mode the clock of the

module is not synchronized. This means audio sam-

ple will be discarded in case the master PCM clock

is faster than the clock of the module or samples will

be repeated in case the master PCM clock is slower.

• MASTER mode. The FP is master on PCM interface

and therefore provides PCM clock and PCM_FSC to

an external device.

4.12.1 PCM Interface for FP

The SC14CVMDECT SF supports PCM interface func-

tionality to connect to an external audio source/destina-

tion.

The different PCM interface modes and timings are

shown in Figure 21 to Figure 26. Refer to document [1]

for detailed information.

4.12.2 PCM_FSC frequency

The PCM interface supports the following options:

• 8 kHz

• 16 kHz

4.12.3 Length of PCM_FSC

The PCM interface supports the following options:

• 1: The length of PCM_FSC pulse is equal to

1 data bit.

• 8: The length of PCM_FSC pulse is equal to

8 data bits.

• 16: The length of PCM_FSC pulse is equal to

16 data bits.

• 32: The length of PCM_FSC pulse is equal to

32 data bits.
