61225101L1-5B 1 Express 6530 SHDSL NxNTU Installation and Maintenance Section 61225101L1-5B Issue 2, December 2002 CONTENTS 1. GENERAL ..................................................................... 1 2. CONNECTIONS .............................
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.
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.
4 61225101L1-5B 2. CONNECTIONS Back Panel Features The back panel of the Express 6530 SHDSL NxNTU is illustrated in Figure 3 . The SHDSL port uses a RJ-45 connector with the interchange circuits and pinouts listed in Table 3 .
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.

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.
10 61225101L1-5B G. 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.
61225101L1-5B 11 Typical Applications Framed Full E1 Service is set up using the quick key “G,” and then selecting “A” to save the changes. The screen in Figure 8 illustrates a cross-connect map configured for Framed Full E1 Service.
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.
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).
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 ).
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.
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.
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.
