A Klang Valley office’s real choice is between a contended GPON circuit (Unifi Business, sharing 1:32–1:64 with residential traffic, no default SLA) and a 1:1 symmetric dedicated link (Maxis Dedicated Fiber, 99.9% SLA, static IP subnet included) — the price gap is roughly 3–5x, and the correct pick depends on whether your office runs real-time VoIP, on-prem servers, and API traffic or just POS terminals, email, and browsing.
Contended GPON vs 1:1 Dedicated: Split Ratio Math
Unifi Business is a standard FTTH/FTTB product on TM’s GPON aggregation. One PON port in a Klang Valley node typically serves 32–64 households and offices. From 8pm to 11pm, when the residential side of Cheras, Puchong, or Shah Alam is streaming, your office’s 300Mbps plan gets whatever interleaving the OLT gives it. Upload is less congested on TM’s newer 10G GPON segments, but downstream latency spikes are measurable — jitter above 15ms begins breaking VoIP calls and Teams audio.
Maxis Dedicated Fiber terminates on a dedicated fibre pair (owned or dark-leased by Maxis) with no contention. A 20Mbps DIA circuit can outperform a 300Mbps Unifi Business line for real-time tools, because 20Mbps of uncontended bandwidth beats 300Mbps of shared capacity with bufferbloat. This matters for a 15-person office running Teams video, cloud accounting (AutoCount, SQL Accounting), and offsite CCTV backup at the same time.
SLA: Paid Add-On vs Standard Guarantee
Unifi Business doesn’t default to an SLA. Without the paid Business SLA add-on (approx. RM100/month), a downed fibre line goes into TM’s residential repair queue — in Kuala Lumpur sub-city areas, that means 24–48 hours, sometimes longer around Jalan Kuching and older shoplot zones. The add-on gives you 99.9% uptime and an 8-hour repair target, but you must buy it upfront and ask for it by name.
Maxis DIA’s 99.9% SLA is written into the contract. Local loop faults carry a 4-hour restoration target, extendable to 8 hours for major cable cuts. Credits are rebated against monthly rental, usually after the first 15 minutes of downtime past the threshold. Note that both providers exclude third-party excavation damage — a known reality along Jalan Ampang and Jalan Sultan Ismail, where contractors cut fibre without notice.
IPs, VLANs, and BGP: The Real DIA Difference
Unifi Business ships with a dynamic public IPv4. A single static IPv4 is a roughly RM50/month add-on; a block of 8 static IPs runs approximately RM200–400/month depending on TM’s current enterprise pricing. There is no BGP peering on any Unifi Business tier. VLAN support requires you to terminate the PPPoE session on your own router (MikroTik CCR, pfSense, FortiGate) and build the segmentation yourself.
Maxis DIA automatically includes a /30 or /29 IPv4 subnet — 1 or 5 usable static IPs — with no monthly add-on. The hand-off is a clean Ethernet VLAN-tagged port, so your firewall can run 802.1Q trunks directly: one VLAN for office Wi-Fi, one for CCTV NVR traffic, one for a guest captive portal. If you own your own ASN and prefix, Maxis can peer BGP on the DIA — useful for IT services companies that need multihoming between two providers without double-NAT workarounds.
Klang Valley Coverage: On-Net Buildings vs Fiber Construction
Unifi Business reaches nearly every office, showroom, and converted shoplot in the Klang Valley — including older stock in Jalan Ipoh, Petaling Street, and Pudu — because TM pulls through existing street infrastructure. If the fibre point is already inside the building, provisioning takes under 5 working days with zero construction fee.
Maxis DIA is densest around Bangsar South, KLCC, TRX, Subang Jaya, and the PJ industrial lots (Jaya One, SS2). For buildings off that footprint, Maxis quotes a one-time fibre construction fee that typically lands between RM3,000 and RM25,000 depending on distance to the nearest POP, plus a 12–24 month lock-in. Provisioning for a non-on-net building runs 10–30 working days because a dedicated port or physical cable must be turned up. A Cheras or Puchong shoplot that TM already reaches is therefore an easy Unifi Business decision; a Sunway or Ara Damansara corporate suite with a server rack should get a DIA feasibility survey first.
Pricing Math: Workloads That Justify the 3–5x Premium
Unifi Business runs from approximately RM199 (100Mbps) to RM499 (1Gbps) per month. For a 5–15 person office running a POS system like StoreHub, Billplz payment pages, Google Workspace, and CCTV — this is the right price and the right product class.
Maxis DIA runs from roughly RM900–1,200 for 20Mbps up to RM2,500–3,500 for 100Mbps. That premium buys stable latency, guaranteed repair time, and IP ownership. A 25-person office with a 3CX phone system, a local MySQL database, or site-to-site VPN between KL and a Johor warehouse will notice the difference in daily operations, not in a benchmark report. The compromise used by many KL IT managers is dual-WAN: Unifi Business 500Mbps at RM299 for bulk downloads and a Maxis DIA 20Mbps for the voice and API VLAN, with failover policy routing on a FortiGate.
