HG 1500 V3.0
4.5.7 Modem via IP
As for the encapsulation of voice transmission on IP routes, the HG 1500 V3.0 can also route
analog data between modems over an IP connection.
This function enables connections to be made between traditional analog modems in IP networks.
The HG 1500 board supports different functions for transferring the information:
Modem over G.711 Voice Codec (recommended)
Like faxes, modems can be used to switch a transparent connection over two networked systems
with the G.711 voice codec.
Special limits in terms of delay, jitter, and packet loss network parameters must be taken into
account for the IP network. This function does not support compressed transmission (G.723).
The transport and security protocols that can be used depend on the modems in operation and
not on the HG 1500
V.90 Standard
The V.90 Standard (56K) is supported in the "modem over G.711" procedure. Please note,
however, that an approximate speed of 56 Kbps is only reached in the downstream direction
Bit Rate Adaptation V.110
The HG 1500 supports V.110 bit rate adaptation to guarantee remote access with GSM terminals
using asynchronous PPP. However, this only supports the conversion of GSM-specific
data transmission speed of 9600 bps into the ISDN bit stream of 64 Kbps.
4.5.8 HiPath Feature Access (HFA)
HiPath Feature Access (HFA) provides telephones connected via IP (such as optiPoint 400)
and compatible telephony software (such as optiClient 130) with all the functions that can also
be used by optiPoint telephones in SCN. For this purpose, CorNet TS protocol – with which the
terminals are addressed – is tunneled over IP.
In connection with a HG 1500 V3.0, IP telephones are then equivalent to the classic optiPoint
telephones on a HiPath system.
