2-2 P/N 480-0049-00-13Chapter 2: Hardware ComponentsHardware DescriptionThe Tenor DX is a stackable/rack mountable device which provides PSTN and PBX connections (through T1/E1/PRI lines), as well as connections to the Ethernet LAN and a PC. The unit provides eight RJ-45 ports inwhich you can connect to a PBX or the PSTN.The unit’s front panel includes connection jacks, LEDs, a reset button, and a diagnostics option; the backpanel includes a power cord connection site, an on/off switch, and a label.Front Panel Connections and Reset OptionsFigure 2-1 Tenor DX Front Panel• Ports 1-8. One RJ-45 jack for each port supports a connection to a line side (PBX) or other customerequipment via upstream T1 or E1 lines, or to the trunk side (PSTN) via downstream T1 or E1 lines.Each T1 line provides 24 channels. For each T1 interface, there are two types of signaling supported:Channel Associated Signaling (CAS) and Common Channel Signaling (CCS). For T1 using CAS, chan-nels 1-24 are available; for T1 using CCS, channels 1-23 are available.Each E1 line provides 30B (Bearer) channels and 1D (Data) signaling channel. For each E1 interface,there are two types of signaling supported: Channel Associated Signaling (CAS) and Common ChannelSignaling (CCS).Adjacent port pairs (i.e., 1/2, 3/4, etc.) are configured by default to connect to each other (power offbypass) when the unit is turned off, or when the unit is in Offline mode. This is the preferred methodwhen connecting one of the lines to a PBX, and its adjacent pair to the PSTN. However, if you have adja-cent port pairs that are connected to smaller devices (i.e., both going to PSTN) in which you do not wantthe two ports to be connected to each other in case of power off or offline, you should set the power offbypass = 0. Each pair of ports (1/2, 3/4, 5/6 and 7/8) have their own online/offline and power off bypasscontrol. See the Tenor Configuration Manager online help or the Command Line Interface (CLI) guidefor specific configuration information.• Reset. Enables you to reset the system.• Diag.

LAN2 Ethernet port is reserved for future use.1 2 3 4 5 6 7 8RESETDIAGCONSOLE POWERALERTLAN 1 LAN 2Line/Act100Line/Act100Port Reset Diag Console PortLAN1/LAN2 |
