In traditional telephony systems, there are two types of interfaces used to connect analog phone lines to digital equipment: FXO and FXS. FXO stands for Foreign Exchange Office, while FXS stands for Foreign Exchange Station. In this article, we will discuss the differences between FXO and FXS interfaces and their applications. FXO Interface: An FXO … Read more
When a call is made between two phones registered on a Cisco Unified Communications Manager Express (CME), the signaling process involves several steps that allow the devices to communicate with each other and establish the call. In this article, we will discuss the signaling process for a call between two phones registered on a CME, … Read more
In networking, IEEE 802.3af and IEEE 802.3at are two standards that are used for Power over Ethernet (PoE). PoE is a technology that allows for the transmission of electrical power along with data over a standard Ethernet cable. This technology eliminates the need for separate power cables, simplifies network installations, and improves device mobility. In … Read more
