OM200G IP PBX — hot-swap cards, 96 analog ports, 496 SIP trunks
Four card slots at 24 lines each give up to 96 analog ports, with hot-swappable cards and gigabit Ethernet. This is the model that scales with the site rather than being sized to it.
- Four card slots of 24 lines — up to 96 analog ports in one chassis
- Cards are hot-swappable, so a failed card is replaced without taking the site down
- 496 SIP trunks with up to 120 concurrent calls each
- Two gigabit Ethernet ports, up from 100M on the smaller models
- Optional PT2400 and PT4800 patch panels for structured cabling
- Choice of single AC, dual AC, single DC or dual DC power
Card options and port combinations
The four slots accept voice interface cards in several mixes, so the analog port count is decided by the cards fitted rather than by the model number alone.
OM200G card combinations
| Card | FXS | FXO |
|---|---|---|
| 24FXS | 24 | 0 |
| 24FXO | 0 | 24 |
| 16FXS + 8FXO | 16 | 8 |
| 12FXS + 12FXO | 12 | 12 |
Each card presents six RJ45 sockets per group, broken out to telephone pairs. Patch panel options take the cabling into a structured frame.
Gigabit networking
The OM200G and OM1000-UC are the two models in the range with gigabit Ethernet; the OM20G, OM50G and OM80E are 100M.
- ETH1 and ETH2 share a single IP address, default 192.168.2.240
- ETH2 can be set as a redundant port — it takes over from ETH1 in about 1.75 seconds
- Alternatively ETH2 works as an internal connection port with its own IP address, or as a dedicated SIP trunk interface
Four power configurations
The model spans single AC, dual AC, single DC and dual DC. Dual supplies are the usual choice for a site where an outage is not acceptable.

Compatibility boundaries
This model uses standard SIP and the interfaces listed in the specification table. Confirm the PBX, SIP provider or platform against those interface notes before the order; where the documentation does not state a value, the table records it as not stated rather than estimating. PoE, analog port variants, power options and card compatibility are fixed at order time.
Handover, spares and support
Extension plan, provisioning and interface language can be prepared before dispatch. Remote support continues after handover. Spare-part, warranty and service terms are confirmed in the quotation for the models and quantity ordered, so they are not printed as a single figure here.
