DSP Resource Card
The DSP (Digital Signal Processor) card is a signal processing resource card; it provides the required signal
processing functions to implement VoIP. The DSP card compresses voice data and generates voice packets
using PacketSaver, Quintum's exclusive multiplexing technology.
For the CMS (14 slot), the chassis supports up to eight DSP cards; the DSP card can occupy any slot except
the CPU/System Controller slot. We recommend you install the first DSP card in slot 13 and the next in slot
12, 11, etc. until you reach slot 6.
Note:
Each DSP Bank contains
an upper and lower LED
Channel support. Each DSP board supports 120 voice channels. A maximum of eight cards can be installed
in a system. Although application specific, the number of calls going VoIP determines how many DSP cards
will be required. In general, two DSP cards are required for each fully-utilized WAN T1 or WAN E1 card. See
Table 2-9 for the required number of DSP cards per various T1 or E1 requirements.
