The Juniper Networks CTP2008 Circuit to Packet platform is a 3-U high, full-rack wide chassis designed for tabletop or shelf installation. It can also be installed in a rack with the supplied rack-mounting kit. The CTP2008 platform has one removable interface module and one removable processor module, and is available in both AC-powered and DC-powered versions. It has a removable fan tray, and airflow is side-to-side. Figure 2, Figure 3, and Figure 4 show the CTP2008 chassis containing the PP332 processor (which requires an RTM card for Ethernet and console port accesses). The new PP833 processor module does not require an RTM card. All PP833 module access is located on the front panel with all CTP serial and T1/E1 ports. If you are upgrading from the old PP310 or PP332 processor to the PP833 processor, the RTM card may be left in the node. But, none of the interfaces (Ethernet or serial ports) on the RTM panel are functional.
The front panel comprises the following components (see Figure 2):
Interface module—Frame processing and forwarding engines.
Processor module—Two slots are available on this module for an optional fiber Gigabit Ethernet or Fast Ethernet PMC module. The primary SC connector is on the left side. For more information about the PMC module, see CTP2000 PMC Module and Installing a PMC on CTP2000 Platforms.
Power supply extractor—Push the button to eject the power supply module.
Clock module—Provides clock distribution between modules when the backplane is in use by voice applications.
Power supply—Use a standard IEC power cord for the AC version. Use a 22-AWG fork terminal connector for the DC version. There is no power redundancy for the AC version and the DC version.
There are no power switches on CTP2000 Series DC models, so a readily accessible disconnect device must be provided as part of the electrical installation of the unit. We recommend the 22-AWG wire for DC power terminals.
Ethernet connection—Provides the 1-Gbps Ethernet connection to the IP network by means of a local Ethernet switch or router.
Console connection—Provides an asynchronous tty connection for locally configuring the CTP Series device. On the PP310 and PP332 processors, you can connect a console directly to the COM2 port (which is an RJ-45 type connector) found on the RTM panel.
