The TN2313AP DSI port board interfaces a DSI trunk to the switch backplane via port slots that are standard for DEFINITY products. The TN2313AP is compatible with previous 24-channel DSI circuit packs, including the TN464F (V19 and below), the TN2464 (V19 and below), and the TN767E DSI, except that it does not provide for packet adjunct capabilities. The TN2313AP supports a variety of applications, including networking of DEFINITY switches, international trunk types, video teleconferencing, and wideband data transmission.  On S8500, S8700, and S8710 Media Servers, this circuit pack does not directly support D-channel signaling and thus does not directly support ISDN-PRI connectivity. However, the TN767 circuit may indirectly support D-channel signaling provided that the central office supports non-facility associated signaling (NFAS). In this case, you use NFAS administration on the server to associate the D-channel of another T1/E1 circuit pack (normally a TN464) with the TN767 circuit pack.  The TN2313AP DSI interface can be configured as 24 channels at 1.544 Mbps. The TN2313 can supply two 8-kHz reference signals to the switch backplane for optional use by the tone clock board in synchronizing the system clock to the received line clock.  The TN2313AP is firmware downloadable.

In R9si systems, the TN2404 processor circuit pack replaces the TN790B. The TN2404 increases both the DRAM memory and the flash memory from 16 to 32 Mb. It is designed to handle errors associated with the EM-BUS and must be used with the C-LAN (TN799) and the Net/Pkt (TN2401) in R9si systems.

N767E DS1 interface, T1 (24 channels) - This circuit pack provides a DSX1-level physical interface to the DS1 facility. The TN767 circuit pack has unpolarized line out (LO) and line in (LI) signal lead pairs.  The TN767 circuit pack supports DS1 rate digital facility connectivity. The circuit pack supports CO, Tie, DID, and off-premises stations (OPS) port types. These port types use the robbed-bit signaling protocol. On DEFINITY CSI and SI Media Servers, this circuit pack supports ISDN-PRI connectivity. For these applications, the signaling D-channel can connect from the TN767 circuit pack to the processor interface by a permanent switched call over the TDM bus.  On S8500 and S8700-series Media Servers, this circuit pack does not directly support D-channel signaling and thus does not directly support ISDN-PRI connectivity. However, the TN767 circuit can indirectly support D-channel signaling provided that the central office supports nonfacility associated signaling (NFAS). In this case, you use NFAS administration on the server. This administration associates the D-channel of another T1/E1 circuit pack, usually a TN464, with the TN767 circuit pack.  The TN767 circuit pack communicates with Avaya IVR. The TN767 also provides the enhanced maintenance capabilities of the 120A channel-service unit (CSU) and the enhanced integrated channel-service unit (ICSU).

• Support for echo cancellation.

The echo cancellation capability of the TN464HP is selectable on a per-channel basis. The TN464HP DS1 interface automatically turns off echo cancellation when the interface detects a 2100-Hz phase-reversed tone generated by high-speed modems (56-kbps). But the interface does not turn off echo cancellation when the interface detects a 2100-Hz straight tone generated by low-speed modems (9.6-kbps). Echo cancellation improves a low-speed data call.  The TN464HP DS1 interface is intended for customers who are likely to encounter echo.  This echo can be over circuits that are connected to the public network. The occurrence of echo is higher if the switch is configured for ATM, IP, or other complex services and interfaces to certain local service providers. These local service providers do not routinely install echo cancellation equipment in all their circuits. A common source of echo is "hybrid" circuits, where conversions between 2-wire analog circuits and 4-wire digital circuits take place. The TN464HP DS1 interface cancels echo with delays of up to 96 milliseconds.

The TN2302AP IP Media Processor circuit pack replaces the TN802B. The TN2302AP requires one slot instead of the three slots required by the TN802B.
