Telkom explains"},"content":{"rendered":"

Telkom<\/a> has responded to concerns over exchange congestion and delays in provisioning IP Connect (IPC) upgrades to Internet service providers (ISPs) that apply for them.<\/p>\n

Following complaints of poor ADSL<\/abbr><\/a> performance from customers, ISPs have indicated that the fault does not always lie with their networks, but can be due to congestion at Telkom\u2019s exchanges.<\/p>\n

Delays in receiving upgrades to their wholesale ADSL capacity \u2014\u00a0a product that Telkom calls IP Connect \u2014 has also been cited as a reason<\/a> for some users experiencing poor performance.<\/p>\n

However, Telkom chief technology officer Alphonzo Samuels<\/a> said that the issue is not so simple.<\/p>\n

Speaking to journalists at a recent Telkom media event in Johannesburg, he said that there was, firstly, no IPC order backlog at Telkom.<\/p>\n

\u201cI would be very happy to give anybody that applies for IPC capacity as quickly as possible,\u201d he said, adding that ISPs are welcome to give him a call if there are any problems in this regard.<\/p>\n

Secondly, Samuels said there are 8 potential points of congestion that might affect an ADSL subscriber\u2019s Internet experience.<\/p>\n

These range from Telkom\u2019s network, to whatever national and international connectivity providers ISPs have elected to use.<\/p>\n

\u201cIt\u2019s easy to blame the [Telkom ADSL] network,\u201d Samuels said.<\/p>\n

He said something he noticed was that not all ISPs were increasing their wholesale ADSL capacity in-line with the IPC discounts Telkom had passed on over the past year.<\/p>\n

In total, the IPC price reductions come to a 50% wholesale cost cut, he said.<\/p>\n

This raised another interesting issue ISPs brought up previously, where\u00a0the reduction in IPC costs had not kept pace with Telkom\u2019s line speed upgrades.<\/p>\n

Many ISPs went so far as to accuse Telkom of anti-competitive behaviour<\/strong><\/a>, suggesting that the free doubling of ADSL speeds was a margin squeeze tactic \u201cclearly calculated to erode competition\u201d.<\/p>\n

Though counter-intuitive, ISPs argued that this was bad for consumers not only because of the anti-competitive issues, but also because it meant they couldn\u2019t feasibly increase their capacity in-line with the demand higher line speeds created.<\/p>\n

Insufficient capacity means an ISP may find itself oversubscribed, potentially offering a sub-par broadband experience.<\/p>\n

Samuels responded by saying that this is a convenient argument, but the bottom-line is that after a 50% reduction in wholesale prices he did not see ISPs ordering double the capacity they had before.<\/p>\n

While Samuels did argue that many ISPs are not completely blameless, nor completely honest when it comes to ADSL performance, he did not pass the buck entirely.<\/p>\n

With Telkom group CEO Sipho Maseko<\/a> in attendance, Samuels committed to his boss that they will communicate exactly what they are doing around contention and IPC when the time is right.<\/p>\n

He hinted that the ongoing roll-out of Telkom\u2019s next-generation network<\/a> will have a beneficial impact on exchange-related congestion issues, and that they have a number of \u201cexciting initiatives\u201d on the cards for Telkom Wholesale.<\/p>\n
