Installation of interface cards

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
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
5.1.3.

Installation of interface modules

(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
