PTX3000 Alarm, Management, and Clocking Cable Specifications and Pinouts

PTX3000 Alarm Relay Contact Wire Specifications

For management and service operations, you can connect the PTX3000 to external alarm-reporting devices through the alarm relay contacts on the craft interface. You must provide a wire with gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm2).

PTX3000 Management Interface Cable Specifications

Table 1 lists the specifications for the cables that connect to the management ports on the Control Board or Routing and Control Board (RCB).

RJ-45 Connector Pinouts for the PTX3000 Auxiliary and Console Ports

The auxiliary and console ports on the Control Board and Routing and Control Board (RCB)(labeled AUX and CON) are RJ-45 receptacles that accept RS-232 (EIA-232) cable. The AUX port connects the Routing Engine or RCB to a laptop, modem, or other auxiliary unit, and the CON port connects the Routing Engine or RCBto a management console. The ports are configured as data terminal equipment (DTE). Table 2 describes the RJ-45 connector pinouts.

RJ-45 Connector Pinouts for the PTX3000 Management Ethernet Port

The management Ethernet port on the Control Board (labeled HOST/ETHERNET) and Rounting and Control Board (RCB) (labeled MGT) is an autosensing 10/100-Mbps/1-Gbps Ethernet RJ-45 receptacle that accepts an Ethernet cable for connecting the Routing Engine or RCBto a management LAN (or other device that supports out-of-band management). Table 3 describes the RJ-45 connector pinouts.

PTX3000 Clocking Port Cable Specifications and Pinouts

The PTX3000 has Centralized Clock Generator (CCG) ports for connection to external clocking devices located on the Control Board and the Routing and Control Board (RCB). See Synchronizing Internal Stratum 3 Clock to External Clock Sources on PTX Series Routers for more information about configuring the PTX3000 to use external clocking devices. See Clock Sources for PTX Series Packet Transport Routers for more information about the supported external clocking sources.

Control Board GPS Port Specifications

The GPS CLOCK ports labeled GPS0 and GPS1 on the front panel of the Control Board can be configured to support 5 or 10-MHz GPS signals. These signals are internally isolated and have surge protection.

Note:

The GPS SYNC ports are reserved for future use.

Note:

The BNC cable assembly must have an integrated 50-ohm terminator.

Table 4 lists the specifications for the cables that connect to the GPS0 and GPS1 ports.

Routing and Control Board GPS Port Specifications

The 5/10 MHz clocking ports labeled 0 and 1 on the front panel of the RCB can be configured to support 5 or 10-MHz GPS signals. The 1 PPS clocking ports labeled 0 and 1 on the front panel of the RCB can be configured to support 1-pulse-per-second (PPS) GPS signals. These signals are internally isolated and have surge protection.

Table 5 lists the specifications for the cables that connect to the 5/10 MHz and 1 PPS ports.

Note:

The SMB cable assembly must have an integrated 50-ohm terminator.

BITS Port Specifications

The Control Board and the RCB both have external building-integrated timing system (BITS) clock interface ports labeled BITS A and BITS B on the front panel. These portsallow you to connect external clock signal sources. These signals are internally isolated and have surge protection.

BITS Port Cable Specifications

Table 6 lists the specifications for the cables that connect to the BITS port.

Note:

The plastic connector at the end of the RJ-48 cable is physically identical to an RJ-45 connector (see Figure 1). You must ensure that the cable pinouts match the pinouts described in Table 7.
