NT8D09 analog message waiting line card The NT8D09 Analog Message Waiting Line card is an intelligent 16-channel analog line card designed to be used with 2-wire terminal equipment such as analog (500/2500-type) telephones, modems, and key systems. This card can also provide a high-voltage, low-current signal on the Tip and Ring pair of each line to light the message waiting lamp on phones equipped with that feature.

Outgoing calls During outgoing calls from the terminal equipment, a channel is seized when the station goes off-hook. This simulates a low-resistance loop across the tip and ring leads toward the lineside T1 card, causing the lineside T1’s receive A bit to be changed from 0 to 1. This bit change prepares the lineside T1 to receive digits.

Note: By default, the SAL feature opens the tip side for 750 m/s in loop start operation. This is configurable in 10 m/s increments. • In order to detect distant end disconnect for calls originating on the lineside T1 card, the “battery reversal” feature within the SAL software must be enabled.

In this case, the lineside T1 card will continue to provide a grounded tip indication (A=0) to the CPE until it detects an open loop indication (A=0) from the CPE, at which time it will provide an open tip indication (A=1).

Multiple cards (up to 64) can be served through one MMI terminal or modem by linking the LEIs through a daisy chain. The MMI is an optional feature, since all E1 configuration settings are performed through dip switch settings or preconfigured factory default settings.

Signaling levels MFC signaling uses pairs of frequencies to represent digits, and is divided into two levels: • Level 1: used when a call is first established and may be used to send the dialed digits. • Level 2: used after Level 1 signaling is completed and may contain such information as the status, capabilities, or classifications of both calling parties.

Introduction The NTAK10 2.0 Mb DTI card is a digital trunk card that provides an IPE-compatible 2.0 Mb DTI interface. This circuit card includes an on-board clock controller that can be manually switched in or out of service. You can install this card in slots 1 through 4 in the MG 1000S. The card is not supported in the MG 1000S Expansion.

Transmit data To transmit data on the carrier, the incoming serial bit stream from the NTAK02 circuit card is converted to 8-bit parallel bytes. The signaling bits are extracted by the signaling interface circuitry. Digital Pad: The parallel data is presented to the pad PROM. The PROM contains pad values, idle code, and A/µ-law conversion.

Clocking modes The clock controller can operate in one of two modes: tracking or non-tracking (also known as free-run). IMPORTANT! clocked to an external reference clock. Circuit Card Description and Installation...
Page 730
Tracking mode There are two stages to clock controller tracking: • tracking a reference, and • locked onto a reference. When tracking a reference, the clock controller uses an algorithm to match its frequency to the frequency of the incoming clock. When the frequencies are very near to being matched, the clock controller is locked onto the reference.

Free-run (non-tracking) In free-run mode, the clock controller does not synchronize on any outside source. Instead, it provides its own internal clock to the system. This mode can be used when the system acts as a master clock source for other systems in the network.

Functional description The QPC841 Quad Serial Data Interface card contains all the logic for four asynchronous serial ports, including the baud rate generators. These serial ports are directly accessed by the system processor using memory reads and writes. The QPC841 Quad Serial Data Interface card contains four universal asynchronous receiver/transmitters (UARTs) and the logic necessary to connect the UARTs to the system processor bus.

Connector pin assignments Connector J1 is connected to port one, and uses the RS-232-C standard DB-25 pinout. Connector J2 is connected to ports two, three, and four, and is a non-standard pinout that requires an adapter cable. An adapter cable (NT8D96) splits the J2 signals out to three standard RS-232-C connectors.

Table 274 Connector J2 pin assignments (Part 2 of 2) Number Port Signal Note 1: In DTE mode, the signals CD, DSR, and CTS are tied to +12 volts (through a resistor) to indicate that the QSDI port is always ready to transmit and receive data. Note 2: In DCE mode, the signals DTR and RTS are tied to +12 volts (through a resistor) to indicate that the QSDI port is always ready to transmit and receive data.
