If you are expanding the number of VoIP or TETRA channels in your system you never need extra

interface cards, just skip this section and go to the telecom wiring chapter.

Upgrading VoIP channels or TETRA channels never requires extra interface cards to be installed

because VoIP telephony and TETRA runs over Ethernet.

For AUDIO / POTS / TDM / ISDN2 / ISDN E1/T1

The interface cards that are already present in your machine may have unused channels left that can

used now. If there are a sufficient number of channels spare, just skip this section and go to the telecom

wiring chapter.

You need to know that the ATP-interface card and the DST-interface card can support 8-, 16- or 24

channels. Basically, these cards are 8 channel cards that can hold up to 2 optional 8 channel interface

modules. Adding hardware channels may only involve adding 8-channel interface modules in situations

where a vacant expansion module position is available on the right type of interface card.

For the hardware installation of interface cards refer to chapter 4

6.1.3.

(This section applies only to ATP- and DST interface Cards)

The ATP- and the DST interface cards have 24 channels but may in fact be populated with only 16 or

even only 8 channels installed. Channel upgrades are possible by the installation of 8 channel interface

modules on the base card:

Base card only

Base card +1 interface module = 16 channels.

Base card +2 interface module = 24 channels.

NOTE : ATP and DST expansion modules are NOT identical

Use MOD_24A on ATP Cards and use MOD_24DB on DST Cards
