DMC (Direct Media Connection) Channels
When the DMC interworking feature is active in an IP network between HiPath 3000 and HiPath
4000, gateway connections are set up over DMC channels. From the user’s perspective, a DMC
channel is a gateway channel that provides a gateway connection between HiPath 3000 and
HiPath 4000. The fact that a DMC channel must serve both a master and slave connection re-
sults in a DSP channel reduction.
Note: The number of gateway channels available (DSP channels) is reduced as soon as the
DMC interworking feature is activated with HiPath 3000/5000 Manager E. In this case, a Digital
Signal Processor (DSP) can only provide up to 80 % of all possible channels (for example: 6
instead of 8 DSP channels, 12 instead of 16 DSP channels, etc, ...).
2.4.8
ISDN Routing/PPP Channels
HG 1500 boards can also be used as ISDN routers. The ISDN router can connect two physi-
cally separate IP networks together via an ISDN line. Channel bundling can be used to adjust
the required bandwidth.
The system reserves the B channels required for ISDN routing and thus restricts the available
gateway channels.
If a large number of IP workpoint clients is required, the HG 1500 board may not also be used
as an ISDN router. In this case, ISDN routing functionality must be assigned to an individual
HG 1500 board.
