The MSG300 series are divided into MSG310 series (plastic shell) and MSG320 series (metallic shell). The MSG300 series can provide 4, 8, 16, 24, or 32 voice interfaces, as required by the number and density of users. The MSG300 series provide 1 GE uplink interface or 1 Combo uplink interface (provided by the MSG320 series), 2 FE downlink interfaces (provided by the MSG310 series), and 3 FE downlink interfaces and 1 GE downlink interface (provided by the MSG320 series) besides the corresponding downlink voice interfaces, thus applicable to various access scenarios. The MSG320 series (16/24/32) with multiple voice interfaces can adopt DC power supply, which greatly expands their application scenarios and meets different requirements on voice services.
