Network Timing Interfaces

The router supports these timing interfaces card (TIC):

  • Cisco 8010 timing interfaces card (8000-TIC)

  • Cisco 8010 timing interfaces card with GNSS (8000-TIC-GNSS)

By default, the router comes with Cisco 8000-TIC. Cisco 8000-TIC-GNSS can also be selected when ordering the router.

Usage guidelines

Some of the guidelines to use network timing interfaces:

  • 1PPS input or output and ToD input or output—The interface is used for input or output of Time-of-Day (ToD) and 1PPS pulses. ToD format includes both NTP and IEEE 1588-2008 time formats.

  • The same RS422 pins for 1PPS and ToD are shared between the input and output directions. The direction for each are independently configurable through software.

  • BITS input or output—The BITS interfaces support clock recovery from either a T1 at 1.544MHz or an E1 at 2.048MHz, configurable by software.

Restrictions

Online insertion and removal (OIR) of a TIC module is not supported when the router is operational.

Cisco 8010 Timing Interfaces Card (8000-TIC)

Cisco 8010 Timing Interfaces Card (8000-TIC) is a pluggable module containing these timing ports:

  • 1PPS port

  • 10MHz port

8000-TIC is DIN 1.0/2.3 jack connector compliant to DIN 41626 specifications.

Cisco 8010 Timing Interfaces Card with GNSS (8000-TIC-GNSS)

8000-TIC-GNSS is a Cisco 8010 Timing Interfaces Card with a GNSS module. 8000-TIC-GNSS has:

  • an in-built ESD protection on all pins

  • these timing ports:

    • GNSS Antenna port

    • 10MHz port

    • 1PPS port

Accuracy

PRTC-B

Primary Reference Time Clock

As packet timing requirements emerged, the ITU-T developed the Primary Reference Time Clock (PRTC) standard for time and phase for transport over a packet network and this standard is known as G.8272.


Note

The performance specified in the following table also applies to the output of the combined PRTC and T-GM function when integrated into a single piece of equipment. Therefore, for both the PRTC-A and PRTC-B, there’s no additional (performance) allowance for the inclusion of the T-GM function.

There is no standard packet timing requirement and it is based on implementation. Some standalone PRTC devices have very-high quality quartz oscillators or even a Rubidium oscillator as an option to allow an option for extended holdover. Redundancy is provided through network design instead of relying on holdover performance from expensive oscillators.

According to the standards, there are only a few differences between the two classes of clock. Meeting those requirements may result in different implementations, which may influence the cost of the device.

To achieve improved performance, PRTC-B is typically implemented with a two-band GNSS receiver instead of a single-band receiver. The “traditional” band for GPS signals in the L1 band, while the newer devices receive signals in the L2 band.

Usage Guidelines

These are some guidelines to follow when using the Cisco 8000-TIC-GNSS:

Surge Protection

  • The Cisco 8000-TIC-GNSS modules have built-in ESD protections on all pins, including the RF-input pin.

  • An extra surge protection may be required if rooftop antennas are to be connected to meet the regulations and standards for lightning protection of countries where the end product is installed.

  • The lightning protector must support a low clamping voltage (less than 600V).

  • A lightning protection must be mounted at the place where the antenna cable enters the building. The primary lightning protection must be capable of conducting all potentially dangerous electrical energy to protective earth (PE).

  • Surge arrestors should support DC-pass and suitable for the Timing Interfaces Card with GNSS frequency range (1227.60MHz and 1.575GHz) with low attenuation.

  • Surge arrestors must support DC-pass and suitable for the GNSS frequency range as per the constellation used with low attenuation.

  • For optimal performance, the Cisco 8000-TIC-GNSS requires a GNSS antenna with built-in Low-Noise Amplifier (LNA). The antenna LNA amplifies the received satellite signals for the following two purposes:

    • Compensation of losses on the cable.

    • Lifting the signal amplitude to the suitable range for the receiver frontend.

    The amplification required is 22dB gain + cable/connector loss + Splitter signal loss.

    The recommended range of LNA gain (- cable/connector loss) is 22–30dB with a minimum of 20dB and a maximum of 35dB, at the connector of the receiver module.

Antenna Sky Visibility

  • The Cisco 8000-TIC-GNSS provides 5V to the active antenna through the same RF input.

  • The Cisco 8000-TIC-GNSS signals can only be received on a direct line of sight between antenna and satellite. The antenna must have a clear view of the sky. For proper timing, minimum of four satellites should be locked.


    Note
    The antenna terminal should be earthed at the building entrance in accordance with the ANSI/NFPA 70, the National Electrical Code (NEC), in particular Section 820.93, Grounding of Outer Conductive Shield of a Coaxial Cable.

  • Use a passive splitter if more than one Timing Interfaces Card with GNSS module is fed from a single antenna.


    Note

    The splitter should have at least one RF port capable of DC-pass, and an antenna should be connected to that port, if the antenna needs to feed power from 8000-TIC-GNSS.

External Alarm Inputs

The router supports four dry contact alarm inputs through an RJ45 jack at the back panel.

The alarm condition is normally open, which indicates that no current flows through the alarm circuit, and the alarm is generated when the current is flowing. Each alarm input can be provisioned as being critical, major, or minor.

USB console

USB console is a single USB 2.0 Type-A receptacle on the front panel of the router that:

  • provides console access to Uboot flash for Cisco software and diagnostics

  • uses the Type-A connector

  • operates as a USB peripheral only to connect to an external host computer, and

  • uses a Type-A to Type-A connector instead of a standard USB cable.

Restrictions

  • The USB console port and RS232 console port are mutually exclusive to each other.

RS232 Console

The RS232 console is a port in RJ45 form factor on the rear panel of the router. This console provides:

  • transmission (Tx),

  • reception (Rx), and

  • ground (Gnd) information.

Online Insertion and Removal

The router supports these online insertion and removal (OIR) operations:

  • When an SFP is removed from a port, there is no effect on the traffic flowing on other ports.

  • When an SFP is installed on a port:

    • there is no effect on the traffic flowing on other ports.

    • the system initializes that port for operation based on the current configuration.

    • if the inserted SFP is incompatible with the current configuration of that port, the port becomes operational only after the configuration is updated.

  • When both the AC and DC power supplies are installed and active:

    • the load may be shared between both the PSUs or a single PSU takes the entire load.

    • when one power supply is not working or the input cable is removed, the other power supply takes the entire load without disruption.

  • Both the PSUs are field replaceable units. When one PSU is removed or installed, there is no functional impact to the router.
