Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
EMS-1 (The ITEC Electronic Modular Switch is an electronic direct control switching system. The modules are combined to form a complete switch or any of the modules can be added to your present Step-by-Step Systems.) EMS-2 (The EMS-2 RURAL SWITCH is a stored program control analog switch designed to be cost-effective in small exchanges.

4G eLTE is Huawei's proprietary derivative of the LTE standard, the "e" standing for "enhanced", intended to provide wireless broadband transmission with peak downlink speeds of 50 Mbit/s and 20 Mbit/s uplink per site in 5 MHz, 10 MHz and 15 MHz frequencies.
SMPS may refer to: Scanning mobility particle sizer, an analytical instrument for aerosol particles; Switched-mode power supply, a type of electronic power supply;
The numbers (RAND, SRES, K c) form the triplet sent back to the MSC. When a particular IMSI requests access to the GSM core network, the MSC sends the RAND part of the triplet to the SIM. The SIM then feeds this number and the K i (which is burned onto the SIM) into the A3 algorithm as appropriate and an SRES is calculated and sent back to the MSC.
The HLR will now start responding to SRI-for-SM requests with a failure, indicating the failure reason, and will automatically add the requesting SMSC's address to the MWD list for the destination party. (However, if the SRI-for-SM message has priority flag set then the HLR will reply with VLR address if available)
The SCOPE Alliance was a non-profit and influential Network Equipment provider (NEP) industry group aimed at standardizing "carrier-grade" systems for telecom in the Information Age, successfully in accelerating the NEP transformation towards Carrier-grade Open Source Hardware, OS, Middleware, Virtualization, and Cloud see table:
