Network Interfaces
– CHAP Authentication Mode: Specify which type of authentication should be used for
the PPP connection (CHAP Client, CHAP Host, CHAP Symmetric, not used).
– CHAP Password: Specify the password to be entered by the user for identification in
the case of CHAP authentication. Data cannot be entered in the field if CHAP authen-
tication is not used.
– PPP User Name: Enter a user name of your choice that should be used for authenti-
cation via PAP or CHAP.
Data Compression:
The STAC and MPPC compression algorithms are available for compressing PPP data pack-
ets. STAC is widely used in the UNIX world, while MPPC is the Microsoft alternative. Both al-
gorithms offer similar compression results. MPPC features a more robust resynchronization
mechanism to deal with packet loss and is the preferred option if transmission quality is low.
Please note that pre-compressed data (.ZIP files) and files containing binary data (for example,
audio/video files, *.exe files, etc.) cannot be compressed further and thereby transmitted quick-
er.
● STAC Data Compression: Specify whether STAC should be used for data compression.
● MPPC Data Compression: Specify whether MPPC should be used for data compression.
Address Translation:
● NAT Enabled: Specify whether the "Network Address Translation (NAT)" function should be
disabled or enabled. The active function supports the following protocols: TCP, UDP, and
ICMP (only in passive mode).
● Address Mapping Enabled: Specify whether the "Address Mapping" function should be dis-
abled or enabled.
QoS Parameters of Interface:
● Bandwidth Control for Voice Connections:Bandwidth control prevents the transmission
rates available from being overbooked with voice connections within a multi-link connec-
tion. In other words when header compression is active, a maximum of five voice connec-
tions (G.729/60 msec or G.723/60 msec) is permitted over a B channel. Select this check
box if you want to activate the "Bandwidth Control for Voice Connections" function. This
function only affects connections from one HG 1500 to another.
● Bandwidth of Connection (Kbps): Enter the required bandwidth of the connection in Kbps.
● Bandwidth Used for Voice/Fax (%): Specify the percentage of bandwidth that should be
used for voice/fax connections. (see also Section 7.1.7, "Quality of Service").
● QoS Capability: Enter the "Quality of Service (QoS)" that is supported by the other party
(Identical, DiffServ or IP Precedence). See also Section 9.3, "Quality of Service (QoS)".
– Identical: Both "DiffServ" and "IP Precedence" are accepted for the evaluation.
