Asymmetric Digital Subscriber Line(ADSL)
just a digital voltage meter measure at the origin, and then at the end of line
A 'grounded-wye' connection describes a wye-connected supply, whose star-point (or common point) is grounded. This is essential in order to ensure stable phase voltages. I'm not sure what you mean by a 'grounded-phase' connection; if you mean a 'grounded-line' connection, then this is a short-circuit to ground from a line conductor.
On a three phase system with a line to line voltage of 13800, a wye connection will give you a voltage of, 13800/1.73 = 7977 volts to ground.

A D channel of Delta. This channel can either be used as 16 Kbps or 64 Kbps connections.
In an ISDN (Integrated Services Digital Network) connection, the 16 Kbps line refers to a B-channel that is used for data transmission. ISDN typically provides two B-channels (each 64 Kbps) and one D-channel for signaling and control. The 16 Kbps line can be utilized for specific low-bandwidth applications, such as voice or data services, allowing multiple channels to be combined for more efficient use of the available bandwidth. This makes it suitable for basic telephony and simple data communications.

Network+ Guide to Networks answer: ISDN
56 kbps is ISDN (Integrated Services Digital Network), which uses a switched circuit to connect from point to point. 45 Mbps is probably DS3.
ISDN: Integrated Services Digital Network DSL: Digital Subscriber Line
Basic Rate ISDN (Integrated Services Digital Network) features two main channels: B channels, which provide 64 Kbps each for voice or data transmission, and a D channel, which operates at 16 Kbps for signaling and control information. It is designed for small businesses and home users, allowing simultaneous voice and data communication over a single line. Basic Rate ISDN supports multiple devices, enabling efficient connection management and enhanced communication capabilities. It also offers improved call quality and lower latency compared to analog lines.
For ISDN (Integrated Services Digital Network), the hardware required typically includes an ISDN terminal adapter or an ISDN modem, which connects to the user's device and the ISDN line. On the software side, users may need drivers or configuration software to manage the connection. In contrast, ADSL (Asymmetric Digital Subscriber Line) requires an ADSL modem or router to connect to the telephone line, and it usually includes built-in software for configuration and management. Additionally, users may need a compatible computer or device with an Ethernet port to connect to the ADSL modem.
No, an ISDN phone is not compatible with a DSL line. ISDN (Integrated Services Digital Network) and DSL (Digital Subscriber Line) are different technologies that serve distinct purposes. ISDN is used for digital voice and data transmission over traditional telephone lines, while DSL provides high-speed internet access. To use a DSL line, you would need a DSL modem and a compatible voice-over-IP (VoIP) service or standard analog phone.
D (Delta) channel: 16 kbpsD-channel takes care of call set-up, call control (call forwarding, call waiting, etc.), and maintenanceControl and maintenance can be done in real-time in D-channel while B-channel is still transmitting data-big elk!
ADSL (Asymmetric Digital Subscriber Line) offers faster internet speeds compared to dial-up and ISDN (Integrated Services Digital Network). While dial-up typically provides speeds of up to 56 Kbps, ADSL can deliver speeds ranging from 1 Mbps to over 100 Mbps, depending on the service plan and distance from the provider's central office. ISDN also offers faster speeds than dial-up, typically around 64-128 Kbps, but still falls short of ADSL's capabilities. Thus, ADSL is the fastest option among the three.
