Pipes for voice and data transmission
The Coral CMUX 128 is a fast, cost effective and suitable alternative to provide interconnection ranging from voice and data transmission in the course of communication. In case of multiple locations, the difference terminals can be connected through fat pipes, with a small pipe dropping at each location (Breakfield & Burkey, 2002). The product assures fast transmission for a wide area interconnectivity as well as interconnection of other voice and data platforms besides being flexible enough to accommodate varying landscape. Further, it is suitable for the service industry that involves a private clientele base by enabling consolidation and investment protection among other operations in the service industry (Breakfield & Burkey, 2002). Since the product accommodates Wide Area Network connectivity, high performance transmission coupled with cost effectiveness would be most suitable for an online travel agent; this is in addition to the fact that it is recommended for the service industry that the online travel agent in this case is part of.
On the other hand, the fiber-optic communication may also offer a better alternative to Coral CMUX 128 since it caters for transmission of information over high bandwidth over remote distances. This is because of its immunity to electromagnetic interference unlike normal cable. It also exhibits high performance in terms of internet connection and transmission telephone signals hence covering voice data as well (Kaminow & Willner, 2010). Both the multimode and single mode cables for optic transmission are less bulky coupled with high speed transmission hence the best alternative for a home office set up. The promising high speed and transmission over long distances coupled with immunity for distortion renders optic fiber a good alternative for an online travel agent in a home office set up.

Viable ISP Connectivity
The suitability of Internet Service Provider connectivity ranges from the alternatives attributed to the cable modem, DSL of the FTTH. First, the cable modem provides Ethernet connectivity to personal computers for establishing connection with routers in different terminals, hence providing broadband access services while transmitting both voice and data (Witowsky, 2002). The cable modem therefore becomes a viable alternative due to establishing wireless connection over terminals hence replacing copper phone wires, in terms of transmission. On the other hand, the DSL embraces a copper-loop transmission, the technology that facilitates transmission of voice data at high speeds of up to 8Mbps (Witowsky, 2002). However, the technology faces a major setback that is linked to its transmission being conducted over telephone wires, which are becoming obsolete with the erosion of the twentieth century technology. For a home office set up, this would only be effective on terms of high-speed transmission but would not be a viable candidate for remote communication over long distances needed by the travel agent.
A better alternative to copper wire transmission is also presented by the Fiber-To-The-Home (FTTH) technology that facilitates delivery of broadband services over fiber optic cables famous for their high performance access and remote interconnection (Witowsky, 2002). This would therefore be the best alternative as an Internet Service Provider while setting up the home office as long as the travel agent subscribes to the network.
VPN and AoIP Alternatives
In the course of setting up a Virtual Private Network (VPN), Avaya Incorporation provides various alternatives towards setting up the private network in a home office. The first viable alternative is the Avaya VPN remote phone that supports high-end VPN gateways including Cisco security avenues that assure viable broadband internet connection for a home office set up. The VPN remote phone also assures security over transmission of data by performing user authentication before allowing access. Other advanced versions of the remote phone include 4610SW, 4621SW and 4625SW models that also host the VPN remote software (Frahim, Santos, & Ossipov, 2014) .
Further, in the home office set up, it would be necessary to consider Voice over Internet Protocol. Cisco systems provide better alternatives ranging from the Early Adopters, Multi-vendor Interoperability and the Integrated IP Voice data networks among other alternatives. For instance, taking to account the packet networks offered by Cisco, specifically the H.323components, various terminals are able to access the Packet Network through PSTN or ISDN into the H.323 gateway before gaining access to the packet network. This therefore becomes a viable alternative especially where the home office set up is intended to serve various terminals with it being the central point ( Cisco Systems - Service Provider Solutions Engineering, 2002 ).
Comparing G.711 and G.729
The G.711 is a waveform speech coder that bears a sampling frequency of 8 kHz with only a 0.125ms arithmetic delay. It deploys the Voice Activity Detection technology and Comfort Noise Generation technology that diminishes the bandwidth usage during silence periods. On the other hand, the G.729 depicts an audio compression and container format that uses the ITU-T technology for compression of audio data (Gallardo, 2015). The algorithm is linked to low band with hence most viable for use in voice over internet protocol. The G.729 therefore probatively outweighs the G.711 algorithm for an alternative in a home office set up.
