ISDN Integrate Service Digital Network Pros: Inexpensive and very versatile Almost everyone can get it Can be used as data and voice Cons: Only 128Kbps When receiving voice call, only 64K Can be bonded for (somewhat)higher speed

Pros:

Inexpensive and very versatile

Almost everyone can get it

Can be used as data and voice

Cons:

Only 128Kbps

When receiving voice call, only 64K

Can be bonded for (somewhat)higher speed

DSL Digital Subscriber Line Pros: Readily available for many businesses Low cost Relatively inexpensive Some providers have business class w/SLA Cons: NOT available(reliably) for some businesses Poor response time during outages Difficult to support

Pros:

Readily available for many businesses

Low cost

Relatively inexpensive

Some providers have business class w/SLA

Cons:

NOT available(reliably) for some businesses

Poor response time during outages

Difficult to support

Wireless Pros: Available even in very small communities Relatively inexpensive Cons: Still developing technology Weather related issues Small rural areas will have hard time providing support quickly Latency can be unacceptable

Pros:

Available even in very small communities

Relatively inexpensive

Cons:

Still developing technology

Weather related issues

Small rural areas will have hard time providing support quickly

Latency can be unacceptable

Cable service Pros: Very fast for the money Large providers have business class service w/SLA Support Already have a service infrastructure to provide service to end user location Cons: More suceptible(compared to T1/DS3/Ethernet/Fiber) to outages Will have equipment owned by the cable provider Support

Pros:

Very fast for the money

Large providers have business class service w/SLA

Support

Already have a service infrastructure to provide service to end user location

Cons:

More suceptible(compared to T1/DS3/Ethernet/Fiber) to outages

Will have equipment owned by the cable provider

Support

T1/DS3 Pros: Widely available Because it is provided by the ILEC, Service is guaranteed Good SLA ISP can "own" the customer Customer can provide their own equipment Can be Point-to-Point for private service Cons: Expensive ILEC infrastructure T1 routers are more expensive Political issues involved between the CLEC and ILEC

Pros:

Widely available

Because it is provided by the ILEC, Service is guaranteed

Good SLA

ISP can "own" the customer

Customer can provide their own equipment

Can be Point-to-Point for private service

Cons:

Expensive

ILEC infrastructure

T1 routers are more expensive

Political issues involved between the CLEC and ILEC

Ethernet Pros: FAST, equipment is readily available Very reliable SLA Duplexing allows synchronous ingress/egress speeds Cons: Distance limitation without signal repeaters or conversion is limited to 100M's costly ILEC can be involved

Pros:

FAST, equipment is readily available

Very reliable

SLA

Duplexing allows synchronous ingress/egress speeds

Cons:

Distance limitation without signal repeaters or conversion is limited to 100M's

costly

ILEC can be involved

Fiber Pros: Very fast with little loss If backed by good company, it has excellent SLA and service Because only large companies can provide service, it is a reliable service Flexibility of types of traffic than can travel over fiber Typically a very redundant/self-healing network Cons: Young technology Not readily available Costly Could be extended outages Equipment is expensive and difficult to configure/support

Pros:

Very fast with little loss

If backed by good company, it has excellent SLA and service

Because only large companies can provide service, it is a reliable service

Flexibility of types of traffic than can travel over fiber

Typically a very redundant/self-healing network

Cons:

Young technology

Not readily available

Costly

Could be extended outages

Equipment is expensive and difficult to configure/support

Perimeter Security

If you do not have it, you WILL be compromised(it is only a matter of time) Very complex dynamic issue Requires constant monitoring Costly for business when an issue occurs Costly to implement and support Better in layers Requires expert personnel/support Host or Software based
