Modem via IP |
| As for the encapsulation of voice transmission on IP routes, the HG 1500 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. |
