Question: What alphabet system was inspired by Etruscan numerals and was used on the Italian Peninsula?

Context paragraphs:
Greek numerals: Greek numerals, also known as Ionic, Ionian, Milesian, or Alexandrian numerals, are a system of writing numbers using the letters of the Greek alphabet.  In modern Greece, they are still used for ordinal numbers and in contexts similar to those in which Roman numerals are still used elsewhere in the West.  For ordinary cardinal numbers, however, Greece uses Arabic numerals.

Gurmukhi numerals: Gurumukhi numerals are the numeral system used in the Gurmukhi script for the Punjabi language in India.  It is a variety of the many Indian numerals and are part of Hindu numeral system.  In the Shahmukhi alphabet used for Punjabi in Pakistan, the Eastern Arabic-Indic numerals are used, similar to Persian and Urdu.

Numerals in Unicode: Numerals (often called "numbers" in Unicode) are characters or sequences of characters that denote a number.  The same Arabic-Indic numerals are used widely in various writing systems throughout the world and all share the same semantics for denoting numbers.  However, the graphemes representing these numerals differ widely from one writing system to another.  To support these grapheme differences, Unicode includes encodings of these numerals within many of the script blocks.  The decimal digits are repeated in 23 separate blocks: twice in Arabic.  Six additional blocks contain the digits again as rich text primarily to serve as a palette of graphemes for specialized mathematical use.  In addition to many forms of the Arabic-Indic numerals, Unicode also includes several less common numerals such as: Aegean numerals, Roman numerals, counting rod numerals, Cuneiform numerals and ancient Greek numerals.

Cuniculus (water channel): A cuniculus, plural cuniculi, is a diversionary water channel, used by ancient civilizations on the Italian Peninsula.  As the general ancient Italian use derives from the Etruscan use, the term has a special significance of Etruscan cuniculi.  The city of Veii was noted for them.  The Italian community of Formello to the north of Veii was named after the numerous cuniculi there.

Eastern Arabic numerals: The Eastern Arabic numerals (also called Arabic–Indic numerals and Arabic Eastern numerals) are the symbols used to represent the Hindu–Arabic numeral system, in conjunction with the Arabic alphabet in the countries of the Mashriq (the east of the Arab world), the Arabian Peninsula, and its variant in other countries that use the Perso-Arabic script in Asia.

Cyrillic numerals: Cyrillic numerals are a numeral system derived from the Cyrillic script, developed in the First Bulgarian Empire in the late 10th century.  It was used in the First Bulgarian Empire and by South and East Slavic peoples.  The system was used in Russia as late as the early 18th century, when Peter the Great replaced it with Arabic numerals as part of his civil script reform initiative.  Cyrillic numbers played a role in Peter the Great's currency reform plans, too, with silver wire kopecks issued after 1696 and mechanically minted coins issued between 1700 and 1722 inscribed with the date using Cyrillic numerals.  By 1725, Russian Imperial coins had transitioned to Arabic numerals.  The Cyrillic numerals may still be found in books written in the Church Slavonic language.

Latin alphabet: The classical Latin alphabet, also known as the Roman alphabet, is a writing system originally used by the ancient Romans to write the Latin language.  The Latin alphabet evolved from the visually similar Cumaean Greek version of the Greek alphabet, which was itself descended from the Phoenician abjad, which in turn was derived from Egyptian hieroglyphics.  The Etruscans who ruled early Rome adopted the Cumaean Greek alphabet which was modified over time to become the Etruscan alphabet, which was in turn adopted and further modified by the Romans to produce the Latin alphabet.

Etruscan numerals: The Etruscan numerals were used by the ancient Etruscans.  The system was adapted from the Greek Attic numerals and formed the inspiration for the later Roman numerals via the Old Italic script.

Egyptian numerals: The system of ancient Egyptian numerals was used in Ancient Egypt around 3000 BC until the early first millennium AD.  It was a system of numeration based on the scale of ten, often rounded off to the higher power, written in hieroglyphs, but they had no concept of a place-valued system such as the decimal system is.  The hieratic form of numerals stressed an exact finite series notation, ciphered one to one onto the Egyptian alphabet.  The Ancient Egyptian system used bases of ten.

Old Italic script: Old Italic is one of several now extinct alphabet systems used on the Italian Peninsula in ancient times for various Indo-European languages (predominantly Italic) and non-Indo-European (e.g. Etruscan) languages.  The alphabets derive from the Euboean Greek Cumaean alphabet, used at Ischia and Cumae in the Bay of Naples in the eighth century BC.
