Relay switch for highly available 
ISDN trunk connection 

The models IP800 and IP6000 are capable of 
forwarding the ISDN trunk connection (BRI or 
PRI) to a further PBX, which enables the trunk 
line to still be available even in case of failure 
by means of a relay switch. For this purpose, 
the IP6000 has four PRI and the IP800 four 
BRI interfaces. Two of these interfaces can be 
used towards the trunk line and serve thus 
sixty or four voice channels, respectively. The 
remaining two interfaces are used to forward 
onto a system which is preferably identical. 
An additional failover switch is thus not neces-
sary. This so-called “Power-off loop” system, 
as shown in figure 13, provides trunk access 
even if the primary system completely fails.

Redundant power supply using PoE 
and integrated mains adapter

The power supply is very simple. The tele-
phone systems and terminals can be oper-
ated using power over Ethernet (PoE) accor-
ding to IEEE 802.3af and need a maximum of 
just 15 watts. Furthermore, all large systems, 

i.e. IP800 and IP6000 have an integrated 
100-240V mains adapter, which can either be 
used as an alternative to the PoE connection 
or to create a redundant power supply. The 
smaller systems can be powered redundant-
ly using external mains adapters. 

Scalable distribution

A further option to improve scalability is th-
rough outsourcing certain media services. 
This enables the functions MoH, dial tone and 
media relay to be distributed amongst various 
physical systems. In order to further increase 
these scalability effects, there is also the pos-
sibility of inter connecting several PBXs to a 
logical media service unit.
