Dynamic Configuration Rules
2.5.4.2.3 IP Trunking via LAN and WAN (ISDN/PPP)
A HiPath 3800 system (head office) is connected to a second system (branch office 1) via an
ISDN connection with 2 PPP channels (S
0
), and to a third system (branch office 2) via a direct
LAN connection.
Voice over PPP with codec G.729 and a sample rate of 60 ms without encryption is implement-
ed for PBX network connection to the second system. Six voice channels are consequently
supported via the two PPP channels (S0).
8 voice channels are sufficient for the PBX networking connection to the third system (branch
office 2). Codec G.729 with a sample rate of 20 ms without encryption is used for this connec-
tion.
At head office, 6+8=14 PBX networking channels must be configured, while 6 PBX networking
channels must be configured at branch office 1, and 8 PBX networking channels configured at
branch office 2.
One STMI2 (2 DSPs on board supporting up to 32 voice channels) is sufficient for this purpose.
