NOTE
The pin-out for the RJ-21 connector follows traditional telephony wiring standards, and is consistent with the pin-out used in Nortel BCM Media Bay Modules (DSM16, DSM32) as well as Norstar Station Modules and can be used with RJ-11 breakout panels such as the Allen Tel AT125-SM Bridging Adapter.
