The Huawei E5172As-22 is the UK and worldwide version of the Huawei E5172 4G Router.
This is the latest high speed 4G wireless broadband router from Huawei and uses the new CAT4 LTE 4G modem with download speeds up to 150Mbps.
The Huawei E5172As-22 provides wireless conectivity for up to 32 users and also inlcudes an RJ45 Ethernet LAN port for wired network connectivity as well as an RJ11 telephone port for the connection of an analogue telephone to make calls over GSM. When making and receiving calls the router will drop down to 2G/3G internet speeds. The E5172 router also inlcudes a VoIP client inside the router configuration so you could use VoIP over 4G to make calls using the attached analogue phone (so the router is working like a VoIP ATA - Analogue Terminal Adapter).
The Huawei E5172 4G Router is a mains powered device but they also provide a battery compartment and connection so you can purchase the optional battery for the E5172 4G Router.
This battery will provide approx 90 minutes of useage.
We have tested this RJ11 Adapter for use with the Huawei E5172s-22 4G Router and we recommend that if you are going to use a telephone with the huawei E5172s-22 router then you purchase this adapter.
We will be unable to provide support or guidance for telephone users who want to choose their own adapter. you will see at the video of the router at www.e5172.co.uk that the phone is fully working to make and receive calls and this is the RJ11 to BT adapter that was used and tested thouroughly.
