Adding Second ADPCM Card
Requirements
• The second ADPCM card must be revision G or later. If the installation is being
made in a T1 system, then both cards must be revision G or later.
• The 2000 Series paging terminal must be running ZPAGE version J or later.
• The dual trunk cards installed must be revision E or later to support 48PCM paths.
Configuration
Prior to installing the second card in the 2000 Series paging terminal, review the settings
shown in Table 25 or Table 26 (whichever applies to your system). Configure the jumpers
on the second ADPCM card as necessary and be sure to check the position of the jumpers
on the first card at the time of installation.
