What is WIC-1T module?

What is WIC-1T module?

Features: The WIC-1T features the Cisco 5 in 1 connector which supports several serial protocols (V. 35, X. 21, RS-232, RS-449, RS-530) when used with the appropriate transition cable. Note: When used in a Cisco 1720 and 1600 series router, the WIC-1T may also be operated in asynchronous mode.

What is the difference between WIC-1T and WIC-2T?

There isn’t any difference in functionality between the two, the only difference is port count. WIC-1T can only do sync serial at a maximum of 2Mbps. The WIC-2T can do 8Mbps on each port concurrently if you plug it into a suitable router. WIC-1T can only do sync serial at a maximum of 2Mbps.

What is E1 CAS?

E1:This is a digital circuit provided by the telco which can be used for voice or data. T1:Same usage as E1. ISDN:This is also a service provided by the telco which can be used for voice or data. CAS:Signalling mechanism which can be used on E1 circuits when the circuit is used for voice purpose.

What is the difference between an E1 and a T1?

E1 links are similar to T1 links except that they carry signals at 2.048 Mbps. Each signal has 32 channels, and each channel transmits at 64 Kbps. E1 links have higher bandwidth than T1 links because it does not reserve one bit for overhead. Whereas, T1 links use 1 bit in each channel for overhead.

What is difference between CAS and CCS?

Digital signaling has two major forms: Channel Associated Signaling (CAS) and Common Channel Signaling (CCS). The major difference is that with CAS the signaling is included in the same channel as the voice call. With CCS the signaling is provided in a separate channel.

What is the difference between CAS and CSS?

CAS uses the same channel as for data, while CCS uses a separate channel. CCS uses interpretive mode, while CAS uses transparent mode. CAS uses a separate channel, while CCS uses the same channel as data. CAS uses master/slave dissemination, while CCS uses a single master reference.

What is the difference between E1 and T1?

T1 is a digital carrier signal that transmits the DS – 1 signal. T1 is the North American term whereas the E1 is the European term for the transmission (digital). The data rate of E1 is about 2 mega bits per second. It has 32 channels at the speed of 64 Kbps.

What is T1 E1?

A T1 connection bundles together 24 64-kbps (DS0) time-division multiplexed (TDM) channels over 4-wire copper circuit. This creates a total bandwidth of 1.544 mbps. An E1 circuit in Europe and other parts of the world bundles together 32 64-kbps channels for a total of 2.048 mbps.

What does wic-1t stand for?

The 1-port serial WAN interface card (WIC-1T) provides serial connections to remote sites or legacy serial network devices such as Synchronous Data Link Control (SDLC) concentrators, alarm systems, and packet over SONET (POS) devices.

What protocols are supported by the hwic-4t?

The 4-port multiprotocol high speed HWIC (HWIC-4T) is illustrated in Figure 6. Protocols supported are Async (SLIP), Async (PPP), HDLC, Bisync, and transparent. Interfaces supported are as follows:

What is a smart serial port on a HWIC?

The 1-port serial HWIC, the 2-port serial HWIC, and the 2-port A/S HWIC have Cisco smart serial ports. Use the correct cable for your serial HWIC. The serial cable attached to a smart serial port determines the port’s electrical interface type and mode (DTE or DCE).

How do I prepare for connecting a HWIC to the network?

Before connecting an HWIC to the network, ensure that the HWIC is installed in the router, the equipment is properly grounded, and you have the proper cables for connecting the HWIC to the network. This section describes the preparation necessary for connecting a 1- and 2-Port HWIC to the network.
