HG 1500 V3.0
MAC Address Filters for Using the Gateway from within the LAN
MAC address filters can limit access to the router from devices within the LAN. When MAC filtering
is activated, only devices within the LAN whose IP and MAC addresses have explicit permission
to do so may set up a connection via the HG 1500 V3.0. (This function cannot be defined
with dynamic IP address allocation in the LAN via BootP or DHCP).
Access Protection for Administrative Access
General administrative access and access to accounting data can each be separately limited
to specific IP addresses, regardless of any other IP filters.
4.5.9.4 Multilink
The HG 1500 V3.0 can set up static or dynamic PPP connections with a remote station via several
B channels simultaneously.
A static multilink uses the same number of B channels for the duration of the connection. A dynamic
multilink adds or removes channels depending on current channel load. These parameters
can be configured.
4.5.9.5 Short-Hold
After a preconfigured time period with no data transfer over a PPP connection, the HG 1500
V3.0 can clear down the connection automatically.
4.5.9.6 IP Control Protocol (IPCP)
The HG 1500 V3.0 supports the IP Control Protocol (IPCP) for dynamic handling of IP addresses
during connection setup.
4.5.9.7 Compression of IP Headers
Significant protocol overhead can develop, especially during voice data transmission where
user data in a packet is typically short. To improve the situations, the HG 1500 V3.0 supports
the compression of IP headers according to RFC 2507 and RFC 2508. The compression is negotiated
during the configuration of the connection with the receiver in accordance with
RFC 1332 and RFC 2509.
4.5.9.8 Data Compression
User data in a PPP connection can be compressed with the STAC or the MPPC algorithm. The
compression for each channel is negotiated separately with the remote station.
