Cisco 6130 NI-2 DSLAM System Connectors

This chapter discusses the receptacles on the backplane of the Cisco 6130 NI-2 DSLAM and on the backpanel of each component of the Cisco 6130 NI-2 DSLAM system. It describes

• Cisco 6130 NI-2 DSLAM receptacles

• POTS splitter receptacles

• Fan tray connectors

For detailed Cisco 6100 system receptacle and connector pinouts, refer to the Cisco 6100 Series Installation Guide.

4.1 Cisco 6130 NI-2 DSLAM Backplane Receptacles

The Cisco 6130 NI-2 DSLAM system supports

• An installation with a Siecor POTS splitter (with DMT-2 ATUC-1-4DMT modules)

• An installation without a Siecor POTS splitter (with DMT-2 ATUC-1-4DMT modules)

Figure 4-1 shows the Cisco 6130 NI-2 DSLAM backplane with the system I/O card installed. Table 4-1 describes the Cisco 6130 NI-2 DSLAM backplane receptacles and connectors.

Table 4-1: Cisco 6130 NI-2 DSLAM Backplane Receptacles and Connectors

Connector Identifier	Name	Function
J45 through J48 (hidden)	---	These 4 receptacles not used.
J49	Fan alarm SCSI receptacle	Supplies fan alarm relay closure information to fan alarm process and indicators of the Cisco 6130 NI-2 DSLAM network interface (NI-2) module.
J39 through J44	xDSL data	In an installation with a POTS splitter, 50-pin Champ reeceptacles are used to transfer digital data between the DSLAM and a Siecor POTS splitter. In an installation without a POTS splitter, these receptacles are used to transfer data between the CO facility main distribution frame (MDF) and the Cisco 6130 NI-2 DSLAM.
P3, P9 (hidden)	System I/O card	Two single hard metric modular connectors on the chassis backplane, and receptacles on the system I/O card, used to connect the system I/O card to the Cisco 6130 NI-2 DSLAM system.
P13	Power	A terminal block connector with four dual power connections (48 VA, 48 VA Return, 48 VB, and 48 VB Return).
P18	Analog test input	A 2-position header for connecting external ADSL test equipment. Note For future use.
P14, P15, and P17 (hidden)	---	These 3 receptacles are not used.

4.2 POTS Splitter Receptacles

Table 4-2 describes connectors on the Siecor POTS splitter back panel.

Table 4-2: POTS Splitter Back Panel Connectors

Connector Name	Connector Group	Description
LINE 1- 24, LINE 25-48, LINE 49-72, LINE 73-96, LINE 97-120, and LINE 121-128	MDF to subscriber line inputs	Six connectors that carry subscriber line inputs from the central office MDF to the Siecor POTS splitter. Refer to Siecor documentation for details.
POTS 1-24, POTS 25-48, POTS 49-72, POTS 73-96, POTS 97-120, and POTS 121-128	POTS outputs	Six connectors that carry POTS voice line outputs from the Siecor POTS splitter to the central office PSTN.
XDSL 1-8, XDSL 65-72, XDSL 9-32, XDSL 33-56, XDSL 57-64, XDSL 121-128, XDSL 73-96, and XDSL 97-120	Cisco 6130 NI-2 DSLAM digital subscriber line inputs	Six connectors that carry DSL digital data inputs from the Siecor POTS splitter to Cisco 6130 NI-2 DSLAM digital data input connectors J39 through J44.

4.3 IOS Interface Connectors

The Cisco 6100 Series DSLAM NI-2 module includes a group of three RJ-type faceplate connectors that provide IOS control ports: CNSL, AUX, and ENET. The ports provide these connections:

• CNSL---Provides connections to a system console. The CNSL console port connector is an EIA/TIA-232 interface configured as a DCE port. Access settings are

  • Baud rate---9600 bps

  • Data bits---8

  • Parity---None

  • Stop bits---1

• AUX---Provides connections to an auxiliary function. The AUX connector is an EIA/TIA-232 interface configured as a DTE and is used to establish the interface between the NI-2 module and display monitors. This allows up to six users to manage a Cisco 6130 NI-2 DSLAM system through serial or Telnet sessions.

• ENET---Provides connections to a system Ethernet. The ENET connector is an RJ-45 10BaseT connector that complies with Ethernet standards.

Figure 4-3 shows a Cisco DS3 type NI-2 module faceplate with console, auxiliary, and Ethernet connectors.

4.4 Fan Tray Connectors

When you install a Cisco 6130 NI-2 DSLAM, additional cooling is required. A fan tray with three fans must be installed below the Cisco 6130 NI-2 DSLAM. Refer to the Cisco 6100 Series Installation Guide for more information about installing a fan tray.

Figure 4-4 shows the fan tray rear panel.

Table 4-3 describes the connectors and J1 receptacle on the fan tray rear panel.

Table 4-3: Fan Tray Backplane Connectors

Identifier	Name	Description
P1	Power	Terminal block connector with four dual power input connections (48 VA, 48 VA Return, 48 VB, and 48 VB Return).
P2	---	Not used.
J1	Alarm	A Cisco 72-1641-01 or 72-1912-01 SCSI cable connected between between the fan tray rear panel receptacle J1 (Figure 4-4) and the Cisco 6130 NI-2 DSLAM backplane receptacle J49 (Figure 4-1) provides the fan tray alarm interface.

Table 4-4 lists fan tray terminal block P1 and Cisco 6130 backplane terminal block P13 terminal relationships. Connect fan tray terminal block P1 terminal -48 VA to chassis backplane terminal block P13 terminal -48 VA. Connect fan tray terminal block P1 terminal -48 VB to Cisco 6130 backplane terminal block P13 terminal -48 VB. Also connect the common returns.
