Mixing DSP Cards in a CSP

Compatibility

IMPORTANT: An MFDSP card may not reside in the same chassis as a DSP Series 2 card.

Card Combinations | Compatible?
--- | ---
MFDSP and DSP-ONE | Yes
DSP-ONE and DSP Series 2 | Yes
MFDSP and DSP Series 2 | No

Function Allocation

In CSPs that use both the DSP-ONE and DSP Series 2 card, DTMF, MFR1, MFR2, and CPT transmitters all use resources from the DSP-ONE first if it is configured for them. The RAN Connect message always uses resources from the DSP-ONE card first. Receivers and Bong Tone are assigned in a round-robin fashion. The chip with the most resources available gets Dynamic Conferencing and Clamped Conferencing first. The chip with the least resources available gets Static Conferencing and Monitor Conferencing first.

DSP-ONE and DSP 2 Sample Configuration 1

The following sample configuration illustrates an CSP with one DSP Series 2 card (with one module) and one DSP-ONE card (with 2 modules)

DSP-ONE card with two DSP Modules

• Seven DSPs DTMF Detection = 154 Ports

• Seven DSPs CPA Detection = 140 Ports

• One DSP DTMF Generation = 2,048 Ports

• One DSP CPA Generation = 2,048 Ports

DSP Series 2 card with one DSP Module

• Two DSPs DTMF Detection and Tone Generation = 1,024 Ports of DTMF Detection, and 1,024 Ports of any tone generation

• Two DSPs CPA Detection and Tone Generation = 1,024 Ports of CPA detection, and 1,024 ports of any tone generation

DSP-ONE and DSP 2 Sample Configuration 2

The following sample configuration illustrates an CSP with one DSP Series 2 card with one module, and one DSP-ONE card with two VRAS modules.

DSP-ONE card with two VRAS Modules

• Three DSPs DTMF Detection = 66 Ports

• Three DSPs CPA Detection = 60 Ports

• One DSP DTMF Generation = 2,048 Ports

• One DSP CPA Generation = 2,048 Ports

• Two VRAS = 104 minutes of announcements and 110 simultaneous channels

DSP Series 2 card with one DSP Module

• Three/two DSP DTMF Detection = 768 Ports

• Three/two DSP CPA Detection = 768 Ports

• One DSP Record/Playback = Virtually unlimited announcement storage, 128 simultaneous channels.
