SL92ML1B

SL92ML1B is an E1 interface board for a Huawei microwave indoor unit on the RTN 950. It plugs into the indoor shelf rather than mounting at the antenna, so this is equipment-room hardware and the install is straightforward compared with anything on the tower.

It provides 16 E1 interfaces at 120 ohm. The smart variant adds per-circuit monitoring and performance measurement rather than passing circuits transparently, which is what lets a fault be attributed to a span instead of being chased end to end.

The RTN 950 is a Huawei microwave platform, and its lifecycle status is genuinely unclear. Huawei’s RTN line as a whole is still an active product family, but the position of this particular model could not be established: Huawei’s lifecycle database sits behind a login and model-level end-of-sale and end-of-support dates are not published openly.

So this page will not tell you the platform is current and will not tell you it is finished, because neither can be checked from outside. If that distinction matters to your purchase, and on microwave it often does because licensed-band links tend to live for a decade, ask us to confirm it with Huawei before you commit.

What to confirm before ordering. Which shelf and software release this is going into, how many radios it has to serve, and whether the capacity you want is also licensed, because Huawei caps microwave throughput by licence as well as by configuration. A shelf physically capable of a rate it is not licensed for looks like a fault and is not one. Tell us the hops, the interfaces and the capacity you need and we will specify the shelf, the boards, the radios and the licences together.

Green Code Technologies supplies Huawei microwave equipment, including indoor shelves, radio units and the licences that set their capacity. We are a supplier of Huawei alongside HPE, Dell, Cisco, Samsung and Netgear, and we would rather confirm a part against Huawei’s own documentation than sell you the wrong one, which on RTN 950 equipment is worth doing. Send us the hops this shelf has to serve, the interfaces you need and the capacity you are licensed for and we will come back with a straight answer.
