System Capacity Enhancements
Notes:1. 64 IP trunks mean – Max 32 SIP trunks and Max 32 H.323 trunks at the same time.2. 64 IP Trunks mean – Max 64 SIP Trunks, but only a Max 32 H.323 Trunks. Total 64 IP trunks at any time
As System Capacity for the TDE100/200 /600 and NCP500/1000 communication platform improves, the DSP implications need to be well understood.

Calls between TDM and SIP Trunks
DSP Impact due to improved MPR Hardware– 64 SIP trunks and 32 H.323 trunks (Total remains 64 Channels)
SIP Trunk CODEC DSP41 DSP161 DSP64
G.711 5 Calls 32 calls 64 calls
G.729 2 Calls 12 calls 50 calls2
Note:1. No improvement for DSP4/16 because DSP
limit has been reached2. Limitation by DSP64, G.729 requires more
DSP resource than G.711.

Calls between IP PT and TDM
DSP Impact due to improved MPR hardware – Calls between IP-PT and ISDN/Analogue CO/DPT/SLT/PS
Note:1. Limit reached due to 113 Channel limit2. No improvement for DSP4 because
not enough DSP capacity.

No improvement for DSP4 because not enough DSP capacity.

IP-CS to SIP Trunk Communication
Note:1. Limit reached due to DSP16 resources.2. IP-CS connection does not support P2P connection. Therefore, IP-CS takes one TDM-IP Channel and IP-Trunk also
takes one TDM-IP Channel – for one call. One IP-CS to IP-Trunk thus takes two TDM-IP Channels. Maximum no. TDM-IP Channels is thus 113/2=56.5 => 56
