Procuro profissional com experiência em configuração do HUAWEI MA5616 com placas VDLE(VDSL2)

[trevizoli]

Pessoal adquirimos uma MA5616 + CCUD + 2 x VDLE, fizemos as configurações básicas e testes em nosso laboratório, onde com uma bobina de 500Metros conseguimos atingir 70Mbps/40Mbps...porém ao instalar em campo estamos com problemas na taxa de upload, não conseguimos fazer com que o modem sincronize com mais de 15Mbps de Upload, mesmo estando a menos de 100 metros.
A Huawei está instalada em um DG de um prédio comercial e ligada aos troncos telefônicos, colocamos um modem VDSL2 em uma sala comercial e fizemos os testes de sincronismo. O Down fica em torno de 70Mbps e o UP no máximo a 14Mbps ou 15Mbps, como o protocolo permite 100/100Mbps...nossa idéia era oferecer planos com Uploads de 40% da taxa de Downloads, mas estamos tendo dificuldades para atingir isso no campo.
Precisamos de alguém que tenha conhecimentos em Huawei e VDSL, para nos ajudar.

VDSL é muito bom onde não sofre nenhum tipo de interferência, mas se estiver a mais de 700 metros, muitas emendas, interferência eletromagnética ou por ondas pode esquecer você não vai consegui usar 70% da capacidade da tecnologia, mas caso sirva de ajuda você pode editar o line profile do equipamento e tentar uma config diferente aí você aplica somente em uma porta para testes e se der certo você aplica nas outras, boa sorte amigo.

Estamos usando em um prédio comercial com boa infraestrutura, tudo novo....vc teria alguma boa config de line-profile? Estou usando a Default. Menos de 100metros de cabos. O Down está muito bom...o problema é o UP....

O que pode estar errado para o Upstream não atingir os 22500kbps propostos no channel-profile.

[DjeiBoy]

Desculpa amigo eu trabalho com placas ADLE(ADSL), a profile do VDSL e muito mais complexa, mas vou estudar essa config para entender melhor como os parâmetros.

Ainda precisa de ajuda?

Obrigado.

Boa Tarde estou trabalhando com essas placas e nos condomínios que instalamos esta chegando ate 60mb de down e 30mb de up e isso dividimos uma para dois condomínios e a distancia de um para outro e de 500m fora a distancia do DG ate o cliente. teria como vc me manda a seu script pra analisar??
