This blog was originally started to better help me understand the technologies in the CCIE R&S blueprint; after completing the R&S track I have decided to transition the blog into a technology blog.

CCIE #29033

This blog will continue to include questions, troubleshooting scenarios, and references to existing and new technologies but will grow to include a variety of different platforms and technologies. Currently I have created over 185 questions/answers in regards to the CCIE R&S track!! Note: answers are in the comment field or within "Read More" section.

Carrier Technology

Carrier Technology - I thought I would put a cheat sheet together for some of the carrier technologies used, this is not a comprehensive list but it is a nice start to one. Please feel free to add any technologies to the comment section below.



OC = Optical Carrier - specification for transmission bandwidth using digital signals carried on SONET (Synchronous Optical Networking)
DS = Digital Signal T-Carrier - is a standard in telecommunications in North America and Japan
E = E -carrier - is a standard in telecommunications in Europe and widely used outside of NA and Japan, improves on T-Carrier used in NA and Japan
HSCSD = High-Speed Circuit-Switched Data - faster than GSM  - used in mobile networks
GSM = Global System for Mobile - Worlds most popular standard for mobile networks
EDGE = Enhanced Data rates for GSM Evolution - is considered pre 3G technology - used in mobile networks
UMTS = Universal Mobile Telecommunications System - 3G technology - used in mobile networks
EV-DO =  Evolution-Data Optimized or Evolution-Data only - uses CDMA and TDMA
DSL = Digital Subscriber Line
