Use an ISDN outlet twice without new cabling
- Dual use without new cabling: Use one RJ45 outlet for two ISDN connections.
- Fast connection: 1x RJ45 plug to 2x RJ45 sockets in cable version.
- Secure setup: Clear pin assignment supports correct mapping.
- Flexible expansion: Separable again at the opposite end using a second port doubler.
The ISDN port doubler splits the contacts of an RJ45 outlet so that two ISDN lines are routed in parallel over the existing run. At the other end, a second port doubler restores the original structure, so both connections are available without having to lay additional cables.
This facilitates quick adjustments in professional IT environments, for on-site setups and service deployments when existing infrastructures should remain unchanged. In companies and public institutions, this allows temporary or permanent use of more connection capacity without interventions in the building environment.
