What is clock rate in digital networks?
The clock rate is the speed at wich the data is transfered from some sender, so the receiving side of the communication must know what this speed of data is, in order to catch the bits in the moment their are happening on the line. Hope it help you best figure out how digital networks works.
What is the clock rate for a serial interface?
When you set the clock rate for a serial interface, you are setting the speed of the interface, in other words, the bandwidth (bandwidth meaning rate of data transfer). When using this command it's in the form of bits: 64000 bits = 64 kb.
Why do we use clock rate?
In computing, the clock rate or clock speed typically refers to the frequency at which the clock generator of a processor can generate pulses, which are used to synchronize the operations of its components, and is used as an indicator of the processor's speed.
What is DCE clock rate?
The speed at which a serial WAN link runs is determined by the 'clock rate', this rate governs the number of bits that can be transferred per second, for example, a clock rate of 64000 would give an overall serial link bandwidth of 64k.

What is clock rate 64000 in Cisco router?
Note: Clock rate sets how many bits can be sent over a given time. If the clock rate is set to 64000, you will never be able to send faster then 64 kbs over the interface.
What is DCE and DTE?
Data Terminating Equipment (DTE) and Data Communication Equipment (DCE) are used to describe two different hardware groups. The term DTE is used primarily for those devices that display user information. It also includes any devices that store or generate data for the user.
What is DCE Cisco?
DCE = Data Circuit-terminating Equipment. 1. In a data station, the equipment that performs functions, such as signal conversion and coding, at the network end of the line between the data terminal equipment (DTE) and the line, and that may be a separate or an integral part of the DTE or of intermediate equipment.
Is a router a DCE or DTE device?
The router is the DTE (Data Terminal Equipment) and the external device is the DCE (Data Communications Equipment), where the DCE provides the clocking.
What is a processor clock?
A computer's processor clock speed determines how quickly the central processing unit (CPU) can retrieve and interpret instructions. This helps your computer complete more tasks by getting them done faster. Clock speeds are measured in gigahertz (GHz), with a higher number equating to higher clock speed.

What is the purpose of clock rate?
The clock rate serves to synchronize the receiver on the other side of the link. Each clock pulse signals the transmission of a bit. Note that it is mainly used in lab setups. In the real world, network providers almost always deliver the clock signal.
Why is clock rate important?
Clock rate is used by the sender/receiver so it "knows" how often signally may change to indicate ones and zeros. Higher clock rates mean higher (faster) bits per second transmission rates. (It's also used to "know" signally boundaries.)
What happens if a Cisco device is not detected?
Even if both devices run at the same value, if they don't have a way of synchronizing their clocks, you may still end up with a phase shift in the signal.
How to configure network clock rate?
To configure the network clock rate (speed) for serial ports 0 or 1 in DCE mode, use the clockratenetwork-clock command in interface configuration mode. To cancel the network clock rate value, use the no form of this command.
How to configure clock rate on WAN?
To configure the clock rate between a WAN interface card (WIC) and the serial communication controllers (SCCs) that are used by the WIC, use the clockrate command in interface ATM configuration mode. To disable the clock rate setting, use the no form of this command.
How to configure DS1 link clock source?
To configure the clock source of a DS1 link, enter the clocksource command in interface configuration, controller configuration, or ATM interface configuration mode . To restore the default line setting, use the no form of this command.
What is a 16 bit CRC?
All interfaces use a 16-bit CRC by default, but also support a 32-bit CRC. CRC is an error-checking technique that uses a calculated numeric value to detect errors in transmitted data. The designators 16 and 32 indicate the length (in bits) of the frame check sequence (FCS). A CRC of 32 bits provides more powerful error detection, but adds overhead. Both the sender and receiver must use the same setting.
How does a DSL WIC work?
The communication between digital subscriber line (DSL) WICs and a host in a router occurs through a device called the SCC. If a host wants to forward data or send any control traffic to a DSL WIC, it uses SCCs. In the same way, if a DSL WIC wants to forward incoming data from a line to the host, it also uses SCCs. Each DSL WIC installed in the router uses two SCCs. One SCC (SCC-A) is used for AAL5 data traffic, and the other SCC (SCC-B) is used for AAL2 and control traffic. The speed at which the SCC transfers data between a host and a WIC depends on the clock rate with which it has been configured. You can configure this clock rate on the basis of the DSL line rate. Even though the DSL upstream and downstream line rate may vary, the clock rate between the SCC and the DSL WIC is the same for both the transmitting and receiving direction. That is, the communication between the SCC and the DSL WIC is synchronous. Therefore, you need to configure only one clock rate for an SCC that will be used for both transmitting and receiving between an SCC and a DSL WIC.
What is the clock rate command?
The clock rate command sets the rate in bits per second on the router that has DCE cable plugged in , the IOS accepts the command, if DTE cable is plugged in, the IOS rejects the command.
Why is clock rate important?
Setting clock rate is important for synchronization as each clock pulse signals the transmission of a bit.
Can a Cisco router be DCE?
Whenever two routers are connected one will act as DTE and the other will act as DCE, the decision is up to the network engineer to specify each router as DCE OR DTE. Network engineer must know functionality of router’s interfaces as DTE and DCE, it is also very important for cisco ccna students who are preparing for ccna exam.
Cisco Bandwidth Command
The Cisco bandwidth command is used to communicate the bandwidth value of an interface to higher-level protocols (Ex. routing protocols).
Speed Command
The explanation for the speed command is actually simpler than the bandwidth command. You can set the speed on some interfaces (hardware dependent). You can set it to 10 Mbps even if the interface is 100 Mbps. This indicates that the interface is allowed to send packets at speeds of up to 10 Mbps.
Clock Rate Command
On serial links, this command is used to set the clock rate. While both ends of the serial link can set the clock rate, the router will only accept the command from the DCE end (usually an ISP modem).
