Configuration Rules for HG 1500 V8 in HiPath 3000 V6
9.4.4 ITSP Connection
HG 1500 supports Internet Telephony Service Provider (ITSP) connections and, as a result,
the use of Internet telephony as of HiPath 3000/5000 V6.0 SMR-09, in particular DSL connec-
tions with DID capacity and a phone number range. A maximum of four active ITSPs are sup-
ported simultaneously.
Gateway channels are needed to connect to an ITSP. The following table shows the number of
gateway channels (DSP channels) needed.
The maximum number of ITSP connections depends on the number of HG 1500 boards and
PDM modules deployed and on the system used.
When using Internet telephony, the HG 1500 board may not be used as a router. Any ITSP con-
nections must be set up over an external router.
9.4.5 MOH Channels (G.711, G.723, G.729)
Pro Codec, which is used for MOH, is reserved a DSP channel on a HG 1500 board. A maxi-
mum of 5 codecs per HG 1500 board can be configured for MOH.
Examples:
● Only the G.711 codec is used for MOH: –> 1 DSP channel needed.
● The G.711, G.723.1, G.729AB codecs are used for MOH: –> 3 DSP channels needed.
The DSP channels used for MOH are no longer available for voice connections.
A limit of 10 IP workpoint clients per HG 1500 board can be provided with MOH at the same
time, regardless of the number of codecs configured. This means that there can be a maximum
of 10 MOH data streams per HG 1500 board. If you need more than 10 MOH data streams si-
multaneously, you must activate MOH on additional HG 1500 boards.
The B channels (DSP channels) used for MOH are license-free.
