2 61225101L1-5B The Express 6530 can be powered from any AC power source ranging from 90 V to 240 V at frequencies of 50 Hz to 60 Hz, or a nominal -48 VDC power source. The SHDSL NTU will be used to provide access to customer premises to E1 or Nx64k leased-line services, as well as primary-rate ISDN. The SHDSL NTU is required to support leased-line[...]

61225101L1-5B 3 The Express 6530 has four front panel pushbuttons. The buttons are protected from accidental operation. The front panel button functions can be disabled via the management interface. It is possible to disable the port select SHDSL option to avoid the possibility of looping the SHDSL port when disabled. Table 2 lists and describes th[...]

61225101L1-5B 5 The local management port is a DB-9 female connector and is labeled V.28. The interchange circuits and pinouts are listed in Table 5 . The local management baud rate will auto-detect between 2400 baud and 57600 baud. See EIA-574, Sec 2.2 and Figure 2.7, with Receive Data, Transmit Data and Signal Ground only. The other pins are inte[...]

61225101L1-5B 9 Cross-Connect Map The purpose of the cross-connect map is to allocate the time slots (TS0s) from the SHDSL loop to user ports (E1, V.35/X.21) and configure framing. The cross-connect maps can be accessed via the VT100 terminal screens. Select “1,” Provisioning , from the Main Menu. Choose to provision the local unit (Selection 1[...]

Full G.703 Service If this quick key command is selected, the cross- connect map will automatically configure the time slots for Full G.703 service, and the framing will be set for transparent. Refer to the Typical Applications subsection for more information. N. Full Nx64k Service If this quick key command is selected, the cros[...]

The screen in Figure 8 illustrates a cross-connect map configured for Framed Full E1 Service. Unframed Full E1 Service is set up using the quick key “G,” entering “1” in both the SHDSL TS0 slot [...]

12 61225101L1-5B Full Nx64k 2 Mbps Service is set up using the quick key “N,” and then selecting “A” to save the changes. The screen in Figure 10 illustrates a cross-connect map configured for Full Nx64k 2 Mbps Service. In addition, when setting up Full Nx64k 2 Mbps Service, the type of line interface must be specified. V.35, V.36, or X.21 [...]

61225101L1-5B 13 Bit Error Rate Test The SHDSL NTU contains a built-in Bit Error Rate Test (BERT). The BERT involves injecting and detecting a Pseudorandom Binary Sequence (PRBS) toward the network on the selected payload (i.e. G.703, Nx64, or entire SHDSL payload). The PRBS used in the SHDSL NTU is PRS15 as defined in ITU-T O.150 and O.151. It is [...]

14 61225101L1-5B Local Customer Transparent Loopback – Provides a loopback at the NTU in the customer direction ( Figure 14 ). Data is passed transparently to the network side. Local Network Transparent Loopback – Provides a loopback at the NTU in the network direction ( Figure 18 ). Data is passed transparently to the customer side. Figure 14.[...]

61225101L1-5B 15 Loopbacks may be initiated via the VT100 test screens, front panel pushbuttons, Nx64K port control leads, or by receiving V.54 or PN127 in-band looping signals. Not all loopback types are available for all ports and port services by all initiating sources. See Table 9 for an overview. A key to the symbols displayed in Table 9 is av[...]

16 61225101L1-5B Multiple Services The NTU supports the configuration of multiple services. These services are routed to either the G.703/G.704 interface or the Nx64k interface. The Nx64k interface supports a single service with 1 <= N <= 36. The G.703 interface (with G.704 framing) supports multiple services (often termed “Stacked E1”). [...]

61225101L1-5B 17 The NTU provides framing on the E1 port as described in G.704 (sections 2.3 and 5) and G.706 (section 4) and G.736. In this mode, the data arriving at the SHDSL interface need not contain any G.704 framing and the NTU generates the framing. One or more services can be routed into time slots 1-31. CRC-4 multiframe may be enabled or [...]
